Cross roller bearing

Cross roller bearing is a special type of bearing with inner ring segmentation and outer ring rotation. Due to the segmented inner or outer rings being fixed together with the cross roller collar after installing the rollers and spacers to prevent separation, the installation of the cross roller collar is simple.
Due to the cross arrangement of rollers, only one set of cross roller collars is needed to withstand loads in all directions, which increases the rigidity by 3-4 times compared to traditional models. Meanwhile, due to the fact that the inner or outer ring of the cross roller bearing is a two-part structure, the bearing clearance can be adjusted, allowing for high-precision rotational motion even when preloaded.
Moreover, due to its unique structure, it is commonly used as joint bearings in industrial robots.
