Product Description

Product Description

GZB roller linear CZPT uses the roller to replace the ball, and the contact mode between the rollers and the raceway changes from point contact to linear contact, which greatly improves the rigidity of the rolling linear CZPT and enables the machine to maintain higher accuracy.GZB roller heavy loading linear CZPT contact angle between roller and raceway is 45°, so it has equal load in 4 directions.Roller cage prevents roller deflecting motion and moves stably. At the same time, it forms the oil film contact between roller and cage, avoid friction among rollers, reduce the heat roller and cage, avoid friction among rollers, reduce the heat precision movement.

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.
