Cross roller bearing is a compact structure bearing with orthogonally arranged cylindrical rollers; it has high rotation accuracy capable of bearing loads in every direction.  

With the cross-roller ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90°V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity and the precision can reach up to P5,P4,P2, despite the minimum possible dimensions of the inner and outer rings
