CRBH series crossed roller bearings

Cross roller bearing is a special type of bearing with inner ring split and outer ring rotating. Since the split inner ring or outer ring is fixed with the cross roller collar after installing the roller and spacer retainer to prevent separation from each other, it is easy to install the cross roller collar. Because the rollers are arranged crosswise, 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 divided into two parts, the bearing clearance can be adjusted, even if preload is applied, it can also obtain high-precision rotation movement. Moreover, due to its special structure, it is commonly used as joint bearing in industrial robots.
