Crossed Roller Bearings

Crossed roller bearing is a special type bearing with split inner ring and rotating outer 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. Usually used as joint bearings in industrial robots.
