Crossed roller bearing is a special type of bearing with divided inner ring and rotating outer ring. Because the divided inner ring or outer ring is fixed with the cross roller ring after the rollers and spacers are installed to prevent separation from each other, the installation of the cross roller ring is simple. Since the rollers are arranged in a crosswise manner, a set of cross-roller collars can withstand loads in all directions. Compared with traditional models, the rigidity is increased by 3-4 times.
At the same time, because the inner or outer ring of the crossed roller bearing has a two-part structure, the bearing clearance can be adjusted, and high-precision rotation can be obtained even if preload is applied. Moreover, due to its special structure, it is used in industrial robots. Usually used as spherical bearings.
