Cross roller slewing bearing is a special type of bearing with inner ring divided and outer ring rotating. Since the split inner ring or outer ring is fixed with the cross roller collar after being installed into the roller and spacer retainer to prevent separation from each other, the operation is simple when installing the cross roller collar. Due to the cross arrangement of rollers, only one set of cross roller collar can bear the load in all directions. Compared with the traditional model, the rigidity is increased by 3 ~ 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing is of two split structure, the bearing clearance can be adjusted, and even if preload is applied, the high-precision rotating motion can be obtained. Moreover, because of its special structure, it is commonly used as joint bearing in industrial robot

Features
Cross Roller Slewing bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.
