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

The rings and balls of all-ceramic deep groove ball bearings are made of silicon nitride (Si3N4) ceramic material. This bearing can be designed as a full ball or with PTFE, PEEK or stainless steel 304/316 cage. PTFE is the default standard cage.
Full ceramic deep groove ball bearings have the characteristics of non-magnetic and electrical insulation, wear-resistant and corrosion-resistant, oil-free and self-lubricating, high temperature and cold resistance, and can be used in extremely harsh environments and special working conditions. It can be used in high temperature environment above 400ºC under the condition of full ball or equipped with stainless steel 316 cage. The PEEK cage can also be used at temperatures above 250°C. For CZPT temperatures (for example, lower than -70°C), full ceramic bearings with PTFE cages or stainless steel 316 cages can be used. Normally, the normal radial clearance is C0. When it is necessary to adapt to the extreme environment, other clearances can be customized.

With Strong Lubrication Linear Xihu (West Lake) Dis. Bearing HGH20CA For  Industrial Automation

Features:
1.High positioning accuracy, high repeatability
The linear guideway is a design of rolling motion with a low friction coeffi cient, and the diff erence between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making. 

2.Low frictional resistance, high precision maintained for long period
The frictional resistance of a linear guideway is only 1/20th to 1/40th of that in a slide guide. With a linear guideway, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for long period.

3.Suitable for high speed operation
Due to the characteristic of low frictional resistance, the required driving force is much lower than in other systems, thus the power consumption is small. Moreover, the temperature rising effect is small even under high speed operation.

4.Easy installation with interchangeability
Compared with the high-skill required scrapping process of conventional slide guide, the linear guideway can offer high precision even if the mounting surface is machined by milling or grinding. Moreover the interchangeability of linear guideway gives a convenience for installation and future maintenance.

  • 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.
