CRB
The crossed roller bearing is a special type of bearing in which the inner ring is split and the outer ring rotates. Since the separated inner ring or outer ring is equipped with rollers and spacer rings, which are fixed together with the cross roller ring to prevent separation from each other, it is easy to install the cross roller bearing. Since the rollers are arranged in a cross, only one set of crossed roller bearings can bear loads in all directions.
Compared with standard bearings, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the crossed roller bearing is a separate structure, the bearing gap can be adjusted, and even if the preload is applied, high-precision rotational movement can be obtained. Moreover, due to its special structure, it is usually used as an articulated bearing in industrial robots.
