What factors should be considered in the design and assembly of crossed roller bearings?

The design and assembly of crossed roller bearings are key links to ensure their performance, life and stable operation of the entire mechanical system, and are also key links to ensure their normal operation and service life.

Design and Assembly of Crossed Roller Bearings

1. Design of Crossed Roller Bearings

Structural Design

The structural design of crossed roller bearings is the basis of their performance. The bearing’s load capacity, running accuracy, friction and wear, and lubrication and sealing factors must be fully considered during design.

The cross arrangement of rollers, raceway shape, cage structure, etc. all need to be carefully calculated and optimized to ensure that the bearings can perform well under various working conditions.

Common types of crossed roller bearings include RB type (inner ring as a whole, outer ring split), RE type (inner ring split, outer ring as a whole), RU type (inner and outer ring as a whole, with mounting holes), RA type (inner ring as a whole, outer ring split, ultra-thin), etc. Each type has its specific application scenarios and advantages.

Material Selection

Material is one of the key factors that determine bearing performance. When selecting materials, it is necessary to consider its strength, hardness, wear resistance, corrosion resistance, and thermal stability.

Common materials include high carbon chromium bearing steel, stainless steel, ceramics, etc. Different materials have different performance characteristics and need to be selected according to the specific use environment and requirements of the bearing.
