Crossed Roller Bearing
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 spacers, it is fixed with the cross roller ring to prevent separation from each other, so the operation when installing the cross roller ring is simple. 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 clearance 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.
