Product Description

General Introduction
 
The RA crossed roller bearing is a high - precision bearing designed for applications requiring excellent rotational accuracy and high rigidity. It can effectively support complex loads, including axial, radial, and moment loads.
 
Structure
 
This bearing features a unique crossed roller structure. The cylindrical rollers are arranged perpendicular to each other at 90° in the V - type raceways, and are separated by spacers. This design enables the bearing to withstand various types of loads in different directions with a single bearing.
 
Material
 
High - quality bearing steel is used for the manufacturing of the inner and outer rings and rollers of the RA series bearing. This material ensures high strength, good wear resistance, and excellent fatigue resistance, thereby prolonging the service life of the bearing.
 
Application
 
The RA crossed roller bearing is widely used in industrial robots, machine tools, measuring instruments, and other fields where high - precision rotation and stable operation are required. It helps to improve the accuracy and reliability of the equipment, and plays a crucial role in ensuring the high - quality operation of the entire system.
