RB30025 crossed roller slewing bearing 300*360*25mm
Crossed roller bearings are a special type of bearing with split inner ring and outer ring rotation. The divided inner ring or outer ring is fixed with the cross roller collar after the roller and the spacer are installed to prevent separation, so the operation is simple when installing the cross roller collar. Because the rollers are arranged in a cross, only one set of crossed roller collars can bear the load in all directions.
Compared with the traditional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if a preload is applied, a high-precision rotary motion can be obtained. Moreover, due to its special structure, it is usually used as an articulated bearing in industrial robots.
