IKO spec CRB5013-80010 crossed roller bearings

Structure and Features
With the cross-roller ring, cylingdrical roller sare arranged with each roller perpendicular to the adjacent roller ,in a 90°V groove, separated from each other by a spacer retainer. This desing allows just one bearing to receive loads in all directions including radial, axial and moment loads
Since the Cross-roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacture machines.
High rotation accuracy
The sapacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotational torque from increasing due to freiction betweent rollers. Unlike conventional types using steel sheet retainers, the cross-roller ring does not cause unilateral contract or roller or seize. Thus even under a preload, the cross-roller ring provides stable rotation.

Since the inner and outer rings are desinged to be separable, the bearing clearance can be adjusted. In addition, a preload can be applied. These features enable accurate rotation.
