Cross roller bearing, because the divided inner ring or outer ring is fixed with the cross roller collar after the rollers and spacer are installed, so as to prevent the cross roller collar from being separated from each other, it is easy to operate when installing the cross roller collar. Because the rollers are arranged crosswise, only one set of crossed roller collars can bear loads in all directions, and the rigidity is improved by 3-4 times compared with the traditional model. At the same time, because the inner ring or outer ring of the crossed roller bearing is of a split structure, the bearing clearance can be adjusted, and even if a preload is applied, high-precision rotary motion can be obtained.

1. Excellent rotation accuracy.
In the internal structure of the cross roller bearing, the rollers are arranged vertically and crosswise at 90 degrees, and a spacer or an isolation block is installed between the rollers, which can prevent the inclination of the rollers from grinding each other. In addition, one side contact phenomenon or locking phenomenon of the roller will not occur; At the same time, because the inner ring and the outer ring are divided, the gap can be adjusted, and even if pre-pressure is applied, high-precision rotary motion can be obtained.
2. Simplified operation and installation.
The outer ring or inner ring, which is divided into two parts, is fixed together after the roller and retainer are installed, so the operation during installation is very simple.
