Cross Roller Bearings
Feb 25, 2016

Crossed roller bearing is a divided, special bearing outer ring rotation. Due to segmentation of the inner or outer ring, loaded roller and interval after the retainer, and cross roller shaft rings are fixed together to prevent separated from each other, so when installing the cross roller collar is simple. Because the roller is staggered, so only 1 set of cross roller collar to withstand loads in all directions, compared with the traditional model, 3~4 times more rigid. Meanwhile, crossed roller bearing inner ring and the outer ring is two-Division structure, bearing clearance can be adjusted, even if the preload is applied, can obtain high-precision rotary motion. Moreover, because of its special structure, industrial robots are commonly used as bearings.
