Definition of crossed roller bearings
Crossed roller bearing is a special type bearing with split inner ring and rotating outer ring. Since the divided inner ring or outer ring is installed with rollers and cage, it is fixed with the cross roller ring to prevent separation from each other, so it is easy to install the cross roller ring. Since the rollers are arranged in a cross, only one set of cross roller rings can bear loads in all directions. Compared with the conventional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained. Moreover, due to its special structure, it is usually used as a joint bearing in industrial robots.
Applications of crossed roller bearing:
•Industrial robot arms, reducers
•Precision machines( turnable table)
•Rotation parts of Machine tools
• Measuring instruments
