Product Description

China Machine Bearings Sch87 CSK12P-2RS Open Type Drawn Cup Needle Roller Bearings

Product Description

Needle bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Despite having a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so The radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions.

Depending on the application occasion, a bearing without an inner ring or a needle roller and cage assembly can be selected. At this time, the journal surface and the housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the load capacity and running performance As with bearings with rings, the hardness, machining accuracy, and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This kind of bearing can only bear radial load

In addition to those listed in the catalog, bearings that can be used for general engineering, such as open-type drawn cup needle roller bearings (1), closed-type drawn cup needle roller bearings
(2), needle roller bearing with inner ring
(3) and needle roller bearings without inner ring/needle roller bearings without inner ring and without a cage
(4), with cage and without cage filled with needle roller bearings

A combined needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components. It has a compact structure, small size, high rotation accuracy, and can withstand a certain axial load while bearing a high radial load. And the product structure is diverse, widely adaptable, and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery, and printing machinery, and can make the mechanical system design very compact and smart

Thrust bearings consist of thrust cage assemblies with needle rollers or cylindrical rollers or balls and thrust washers. Needle rollers and cylindrical rollers are held and guided by thrust cages. When used with different series of DF thrust bearing washers, many different combinations are available for bearing configurations. Due to the selection of high-precision cylindrical rollers (needle rollers) to increase the contact length, this bearing can obtain high load capacity and high rigidity in a small space. Another advantage is that if the surface of the adjacent part is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surfaces of the needle rollers and cylindrical rollers used in DF thrust needle roller bearings and thrust cylindrical roller bearings are Modified face to reduce edge stress and increase service life

Differences between Open-Type and Closed-Type Linear Bearings

Open-type and closed-type linear bearings are two common variations used in linear motion systems, each with its own advantages and considerations:

  • 1. Open-Type Linear Bearings:

Open-type linear bearings, as the name suggests, have an open design that allows easy access to the bearing’s rolling elements and raceways. These bearings are characterized by:

  • Quick Maintenance: Open-type bearings are easier to clean, lubricate, and inspect due to their open structure, making maintenance more convenient.
  • Increased Contamination Risk: Because they are exposed, open-type bearings are more susceptible to dust, debris, and contamination, which can affect their performance and lifespan.
  • 2. Closed-Type Linear Bearings:

Closed-type linear bearings are enclosed within a housing or carriage that provides protection from external elements. These bearings offer the following features:

  • Enhanced Contamination Protection: Closed-type bearings are less vulnerable to contaminants and offer improved protection against dust, dirt, and debris, leading to longer service life.
  • Reduced Accessibility: Maintenance and inspection of closed-type bearings might be more complex due to the need to disassemble the housing or carriage for access.
  • Reduced Noise: The enclosed design of closed-type bearings can contribute to reduced noise levels, which is advantageous in noise-sensitive applications.

Choosing between open-type and closed-type linear bearings depends on the specific requirements of the application. If easy maintenance and accessibility are crucial, open-type bearings might be preferred. On the other hand, closed-type bearings offer better protection against contaminants and reduced noise, making them suitable for environments where cleanliness and quiet operation are essential.

Product Description

Product Description

The aligning ball bearings are mainly used to bear radial loads. While bearing radial loads, they can also bear a small amount of axial loads, but generally cannot bear pure axial loads. Their limiting speed is lower than that of deep groove ball bearings. Bearings are mostly used on double support shafts that are easy to bend under the action of load, and in parts with double bearing holes that cannot guarantee strict coaxiality, but the relative inclination of the centerline of the inner ring and the centerline of the outer ring must not exceed 3 degrees.

Differences between Open-Type and Closed-Type Linear Bearings

Open-type and closed-type linear bearings are two common variations used in linear motion systems, each with its own advantages and considerations:

  • 1. Open-Type Linear Bearings:

Open-type linear bearings, as the name suggests, have an open design that allows easy access to the bearing’s rolling elements and raceways. These bearings are characterized by:

  • Quick Maintenance: Open-type bearings are easier to clean, lubricate, and inspect due to their open structure, making maintenance more convenient.
  • Increased Contamination Risk: Because they are exposed, open-type bearings are more susceptible to dust, debris, and contamination, which can affect their performance and lifespan.
  • 2. Closed-Type Linear Bearings:

Closed-type linear bearings are enclosed within a housing or carriage that provides protection from external elements. These bearings offer the following features:

  • Enhanced Contamination Protection: Closed-type bearings are less vulnerable to contaminants and offer improved protection against dust, dirt, and debris, leading to longer service life.
  • Reduced Accessibility: Maintenance and inspection of closed-type bearings might be more complex due to the need to disassemble the housing or carriage for access.
  • Reduced Noise: The enclosed design of closed-type bearings can contribute to reduced noise levels, which is advantageous in noise-sensitive applications.

Choosing between open-type and closed-type linear bearings depends on the specific requirements of the application. If easy maintenance and accessibility are crucial, open-type bearings might be preferred. On the other hand, closed-type bearings offer better protection against contaminants and reduced noise, making them suitable for environments where cleanliness and quiet operation are essential.

Managing Contamination and Debris in Linear Bearings

Contamination and debris pose significant challenges to the proper functioning of linear bearings. However, various measures are employed to effectively manage these issues:

  • Preventive Sealing:

Linear bearings are often equipped with protective seals that act as barriers against contaminants. These seals prevent dust, dirt, and other particles from entering the bearing housing, thus reducing the risk of contamination.

  • Shielding:

Linear bearings can incorporate shields that offer an additional layer of protection against debris. Shields are designed to keep larger particles away from the bearing’s rolling elements, enhancing the bearing’s longevity.

  • Wipers and Scrapers:

Some linear bearings feature wipers or scrapers that actively remove debris from the bearing’s moving parts. These components help prevent the accumulation of contaminants that could compromise performance.

  • Regular Maintenance:

Periodic inspection and cleaning are crucial to maintaining the cleanliness of linear bearings. Routine maintenance procedures help identify and remove any foreign particles that may have entered the bearing housing.

  • Clean Environment:

Creating a clean operating environment is essential. In applications where contamination is a concern, steps are taken to minimize the presence of dust, dirt, and other pollutants in the vicinity of the linear bearings.

  • Proper Lubrication:

Lubrication not only reduces friction but also creates a barrier against contaminants. The lubricant can help prevent particles from adhering to bearing surfaces, facilitating their removal during maintenance.

  • Regular Inspections:

Frequent visual inspections can help identify early signs of contamination. Timely detection allows for prompt cleaning and maintenance, preventing further damage.

  • Appropriate Sealing Materials:

Using high-quality sealing materials that are resistant to wear and tear is essential. The right materials can effectively keep contaminants out while withstanding the operating conditions.

  • Choosing Suitable Environment:

Where possible, placing linear bearings in environments with lower levels of contamination or installing additional protective measures can help manage debris-related challenges.

By implementing these strategies, engineers and operators can effectively manage the challenges associated with contamination and debris, ensuring the optimal performance and longevity of linear bearings.

Advantages of Linear Bearings over Other Bearing Types

Linear bearings offer several distinct advantages when compared to other types of bearings, particularly in applications that require controlled linear motion. These benefits contribute to their widespread use across various industries:

  • Precise Linear Motion:

Linear bearings are designed specifically for linear motion, providing accurate and controlled movement along a defined path. This precision is essential in applications that demand accurate positioning and repeatability.

  • Low Friction:

Linear bearings are designed to minimize friction during motion. The reduced friction translates to smoother movement, reduced wear, and improved efficiency, making them suitable for applications requiring consistent motion.

  • High Load Capacity:

Linear bearings can handle significant loads in both radial and axial directions. This capability allows them to support heavy components and maintain stability under various loads.

  • Minimal Maintenance:

Due to their design and minimal contact between moving parts, linear bearings require less maintenance compared to other types of bearings. This is particularly advantageous in hard-to-reach or inaccessible areas.

  • Guided Motion:

Linear bearings provide guided and constrained motion along a single axis. This guidance eliminates the need for complex guiding mechanisms, reducing design complexity and simplifying assembly.

  • Compact Design:

Linear bearings have a compact form factor, making them suitable for applications with limited space. Their small footprint allows for efficient use of available area.

  • Low Noise and Vibration:

Linear bearings generate minimal noise and vibration during operation, contributing to quieter and more comfortable working environments in applications such as medical devices and precision machinery.

  • Smooth Movement:

Linear bearings offer smooth and consistent movement, essential for applications requiring continuous and controlled motion, such as robotic systems and conveyor belts.

  • Customization:

Linear bearings can be designed to fit specific application requirements, including load capacity, travel distance, and environmental conditions. This customization enhances their suitability for diverse applications.

  • Reduced Wear:

The low friction and guided motion of linear bearings result in reduced wear on both the bearing and the mating surface, leading to longer service life and reduced maintenance costs.

Overall, the benefits of using linear bearings make them a preferred choice in applications that demand accurate linear motion, efficient load handling, and reduced maintenance. Their ability to deliver precision, stability, and reliability contributes to improved performance across various industries.

Choosing the appropriate type and size of linear bearing requires careful consideration of various factors to ensure optimal performance and compatibility with the application. Here are important considerations to keep in mind:

  • 1. Load Capacity:

Determine the maximum load the linear bearing will need to support. Consider both static and dynamic loads to select a bearing that can handle the expected weight and forces.

  • 2. Speed and Acceleration:

Assess the required speed and acceleration of the linear motion. Different linear bearing types have different speed limitations, so choose one that can accommodate the desired motion profile.

  • 3. Precision and Accuracy:

If your application requires precise positioning, choose linear bearings that offer high accuracy and repeatability. Linear ball bearings are known for their precision, while linear roller bearings offer higher load capacity.

  • 4. Environment:

Consider the operating environment, including temperature, humidity, dust, and potential exposure to chemicals. Select linear bearings that are designed to withstand the specific environmental conditions.

  • 5. Rail or Shaft Compatibility:

Ensure that the chosen linear bearing is compatible with the rail or shaft you intend to use. Proper fit and alignment are crucial for smooth motion and long bearing life.

  • 6. Space Constraints:

If your application has limited space, choose compact linear bearings that can fit within the available area without compromising performance.

  • 7. Maintenance Requirements:

Consider the level of maintenance your application can accommodate. Some linear bearings are self-lubricating, reducing the need for frequent maintenance.

  • 8. Noise Level:

For noise-sensitive environments, opt for linear bearings that provide quiet operation to avoid disruptions caused by excessive noise.

  • 9. Mounting Options:

Consider how the linear bearing will be mounted and integrated into your system. Different bearings may require specific mounting configurations.

  • 10. Cost and Budget:

Balance the desired features and performance with your budget constraints. While high-performance linear bearings may offer advanced features, they can also come at a higher cost.

By carefully evaluating these factors, you can choose the most suitable type and size of linear bearing for your specific application. Consulting with bearing manufacturers and engineers can also provide valuable insights to ensure the optimal selection.

Design Principles and Functionalities of Linear Bearings

Linear bearings are designed with specific principles to facilitate controlled linear motion along a single axis. These design principles contribute to their functionalities, making them essential components in various applications:

  • Rolling Elements:

Linear bearings typically feature rolling elements, such as balls or rollers, that move along a track or rail. These rolling elements reduce friction and enable smooth linear motion.

  • Guiding Mechanism:

Linear bearings incorporate a guiding mechanism to constrain the motion to a single axis. This guiding mechanism ensures that the linear bearing moves precisely along the desired path.

  • Load Distribution:

The design of linear bearings allows for effective distribution of loads, both in the radial and axial directions. This load distribution ensures stability and prevents excessive stress on individual components.

  • Rail or Track:

Linear bearings typically run along a rail or track that provides a smooth and accurate path for the rolling elements. The rail is designed to resist wear and maintain its precision over time.

  • Cage or Carriage:

Linear bearings use a cage or carriage to house the rolling elements and maintain their proper spacing. This arrangement ensures even load distribution and smooth movement.

  • Sealing and Lubrication:

Linear bearings often incorporate sealing mechanisms to protect the rolling elements from contaminants and to retain lubrication. Proper lubrication ensures smooth motion and extends the bearing’s lifespan.

  • Mounting Options:

Linear bearings are designed to be mounted in various ways, depending on the application’s requirements. Mounting options include flange-mounted, base-mounted, or end-supported configurations.

  • Adjustability:

Many linear bearings are designed with provisions for adjustment, allowing users to fine-tune the preload or clearance to optimize performance and minimize play.

  • Materials:

Linear bearings are constructed from materials that offer high wear resistance, durability, and corrosion resistance. Common materials include steel, stainless steel, and various engineering plastics.

  • Accessories:

Accessories such as end caps, seals, and lubrication systems can enhance the functionality and lifespan of linear bearings by providing protection and ensuring proper maintenance.

Functionalities of linear bearings include providing precise linear motion, guiding components along a defined path, minimizing friction, distributing loads, and maintaining stability. The design principles ensure reliable operation and make linear bearings indispensable in applications requiring controlled and accurate linear motion.

Tapered roller bearings are bearings that can take large axial forces (i.e., they are good thrust bearings) as well as being CZPT to sustain large radial forces.
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.
The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
The larger the half angles of these cones the larger the axial force that the bearing can sustain.
Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup.

Challenges and Solutions for Addressing Friction and Wear in Linear Bearings

Friction and wear are common challenges in linear bearings that can impact their performance and lifespan. Here are the challenges and some solutions to address them:

  • 1. Challenge: Friction:

Friction between the bearing components can lead to increased energy consumption, heat generation, and reduced efficiency.

  • Solution: Lubrication:

Proper lubrication is essential to minimize friction. Lubricants reduce the contact between moving parts, allowing smoother motion and reducing wear. Choosing the right lubricant and applying it correctly can significantly mitigate friction-related issues.

  • 2. Challenge: Wear:

Continuous movement can lead to wear on the bearing surfaces, affecting precision and performance over time.

  • Solution: Regular Maintenance:

Implementing a regular maintenance schedule can help monitor wear and replace worn components before they compromise performance. This includes cleaning, re-lubrication, and periodic inspection of the bearing’s condition.

  • 3. Challenge: Contaminants:

Dust, debris, and foreign particles can enter the bearing system, leading to increased friction and accelerated wear.

  • Solution: Sealing and Protection:

Using seals, covers, or protective enclosures can help prevent contaminants from entering the bearing system. These protective measures maintain the integrity of the lubricant and extend the bearing’s lifespan.

  • 4. Challenge: Improper Installation:

If linear bearings are not installed correctly, misalignment and uneven load distribution can contribute to friction and wear.

  • Solution: Precise Installation:

Follow manufacturer guidelines for proper installation, ensuring accurate alignment and even load distribution. This reduces the risk of premature wear and ensures optimal performance.

  • 5. Challenge: Inadequate Lubrication:

If the linear bearings are under-lubricated or over-lubricated, it can lead to increased friction and wear.

  • Solution: Lubrication Management:

Monitor and manage lubrication levels to ensure they are within the recommended range. Regularly assess the lubricant’s condition and replenish as needed to maintain optimal performance.

  • 6. Challenge: High Loads and Speeds:

High loads and speeds can increase friction and wear on linear bearings.

  • Solution: Proper Selection:

Select linear bearings that are designed to handle the specific loads and speeds of the application. This ensures that the bearings can operate effectively under the given conditions.

Addressing friction and wear challenges in linear bearings requires a combination of proper maintenance practices, appropriate lubrication, protective measures, and careful selection of bearings. By implementing these solutions, the performance and longevity of linear bearings can be optimized.

Differences Between Linear Ball Bearings and Linear Roller Bearings

Linear ball bearings and linear roller bearings are two distinct types of linear bearings, each with its own design and characteristics. Here’s how they differ and when they are preferred:

  • 1. Design:

Linear ball bearings use ball bearings to provide rolling motion along the shaft. Linear roller bearings, on the other hand, use cylindrical or needle rollers for motion. Roller bearings have a larger contact area, distributing the load over a broader surface.

  • 2. Load Capacity:

Linear roller bearings typically have a higher load-carrying capacity compared to linear ball bearings. This makes them suitable for applications with heavier loads and greater force requirements.

  • 3. Friction and Smoothness:

Linear ball bearings offer lower friction and smoother motion due to the point contact between the balls and the shaft. Roller bearings may have slightly higher friction but can handle larger loads without sacrificing smoothness.

  • 4. Precision and Accuracy:

Linear ball bearings are often preferred for applications requiring high precision and accuracy. Their point contact provides precise positioning and repeatability, making them suitable for tasks like CNC machining and optical systems.

  • 5. Noise and Vibration:

Linear ball bearings tend to generate less noise and vibration due to their smoother rolling action. Roller bearings may produce slightly more noise but are still used in applications where noise is not a critical factor.

  • 6. Speed:

Linear ball bearings are well-suited for high-speed applications due to their low friction and smooth motion. Roller bearings are also capable of high speeds but may have slightly different characteristics.

  • 7. Cost:

Linear ball bearings are often more cost-effective for lower-load and precision applications. Linear roller bearings may be preferred for heavy-duty applications, which may justify their higher cost.

  • 8. Application Scenarios:

Linear ball bearings are commonly used in applications where precision, smooth motion, and accuracy are paramount, such as in CNC machinery, 3D printers, and optical systems. Linear roller bearings excel in applications with higher loads, such as heavy machinery, material handling, and industrial automation.

In summary, the choice between linear ball bearings and linear roller bearings depends on the specific requirements of the application. Each type has its strengths and weaknesses, and selecting the right type ensures optimal performance and longevity.

Contribution of Linear Bearings to Smooth Movement of Conveyors and Slides

Linear bearings play a crucial role in ensuring the smooth movement and operation of industrial conveyors and linear slides. Their contributions are as follows:

  • Reduced Friction:

Linear bearings are designed to minimize friction between moving components, facilitating smooth motion of conveyors and linear slides. This reduces wear and tear, energy consumption, and the need for frequent maintenance.

  • Precision Movement:

Linear bearings enable precise positioning and controlled movement. This precision is vital for conveyors and slides that require accurate placement of materials, products, or components.

  • Stability and Load Distribution:

Linear bearings distribute loads evenly across the bearing surface, enhancing stability and preventing uneven wear. This is especially important for conveyors that handle varying loads and linear slides that support heavy components.

  • Quiet and Vibration-Free Operation:

Linear bearings contribute to quiet and vibration-free operation. This is crucial in environments where noise reduction and minimal vibrations are essential for the comfort of operators and the integrity of products.

  • Efficient Energy Transfer:

Linear bearings ensure efficient energy transfer by reducing energy losses due to friction. This efficiency is particularly beneficial in systems where multiple conveyors or slides are connected, improving overall system performance.

  • Longevity and Reliability:

Linear bearings enhance the longevity and reliability of conveyors and slides by reducing wear on moving parts. This results in extended operational lifespans and reduced downtime for maintenance.

  • Flexibility and Customization:

Linear bearings come in various designs and sizes, allowing for customization to suit specific conveyor or slide requirements. This adaptability is valuable for accommodating different loads and motion profiles.

  • Wide Range of Industries:

Linear bearings find application in industries such as manufacturing, logistics, packaging, and material handling, where conveyors and linear slides are essential components of the workflow.

In summary, linear bearings contribute significantly to the efficient, precise, and reliable movement of industrial conveyors and linear slides. Their ability to reduce friction, ensure stability, and support heavy loads enhances the overall performance of these systems.

Factors to Consider When Selecting a Linear Bearing

Choosing the right linear bearing for a specific application involves considering several critical factors to ensure optimal performance and longevity:

  • Load Requirements:

Determine the magnitude and direction of the loads the linear bearing will experience. Consider both static and dynamic loads to select a bearing with an appropriate load capacity.

  • Precision and Accuracy:

For applications requiring precise positioning, choose linear bearings with high precision and low backlash. Factors like repeatability and positional accuracy are crucial.

  • Speed and Acceleration:

Consider the speed and acceleration at which the linear bearing will operate. Higher speeds may require bearings with lower friction and better heat dissipation.

  • Environmental Conditions:

Assess the environmental factors such as temperature, humidity, and exposure to contaminants. Choose linear bearings with suitable materials and seals to withstand the conditions.

  • Space Constraints:

Take into account the available space for mounting the linear bearing. Some applications may have limited space, necessitating compact and lightweight bearing options.

  • Maintenance Requirements:

Consider the maintenance needs of the bearing. Bearings with self-lubricating properties or easy access for lubrication can reduce maintenance frequency.

  • Mounting and Configuration:

Choose a linear bearing that can be easily mounted and integrated into your system’s design. Consider factors like mounting orientation and available mounting surfaces.

  • Life Expectancy:

Estimate the expected lifespan of the linear bearing based on the application’s requirements. Select a bearing with a suitable design life to prevent premature failures.

  • Cost and Budget:

Balance the desired performance with the available budget. Opt for linear bearings that provide the necessary features without exceeding cost limitations.

  • Accessories and Add-ons:

Consider any additional accessories or add-ons, such as seals, lubrication systems, or end caps, that can enhance the bearing’s performance and protection.

  • Manufacturer and Supplier:

Choose reputable manufacturers and suppliers that offer reliable products and good customer support. Quality assurance and technical assistance are essential.

Overall, a comprehensive assessment of these factors will help you select the most suitable linear bearing for your specific application, ensuring optimal performance, longevity, and cost-effectiveness.

Cylindrical Roller Berings

In bearings of Cylindrical Roller Berings the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.

Cylindrical roller bearings, in which either the inner or outer rings has 2 CZPT and the other ring has one, are capable of taking some axial load in 1 direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools. Some cylindrical roller bearings have no CZPT on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings.

There are different types designated as NU, NJ, NUP, N, NF (for single-row cylindrical roller bearings), NNU, and NN (for double-row cylindrical roller bearings depending on the design or absence of side ribs). The outer and inner rings of all types are separable .
