Excellent rotational accuracy. Spacers or spacers are installed between the rollers to prevent the rollers from tilting or rubbing against each other, effectively preventing the increase of rotational torque. There will be no contact or locking of the rollers. At the same time, because the inner and outer rings are divided, the gap can be adjusted, and high-precision rotational motion can be obtained even if preload is applied.

Simplified operation and installation

The outer ring or inner ring divided into two parts is fixed together after the rollers and retainers are installed, so the operation is very simple during installation.

Bearing large loads

Because the rollers are arranged perpendicular to each other on the 90° V-groove rolling surface through the spacer, this design allows the cross roller bearing to withstand large radial loads, axial loads, moment loads and other loads in all directions.

Greatly save installation space

The inner and outer rings of the cross roller bearing are miniaturized, especially the ultra-thin structure is close to the limit of small size, and has high rigidity, so it is very suitable for the joints or rotating parts of industrial robots.
