Features of crossed roller bearings

1.Structure features:

With the Cross Roller Bearing, cylindrical rollers are aranged croswise, 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, it is optimal for applications such as joints and swiveling uits of industrial robots, swiveling tables ofmachinine centers, precision rotary tables, medical eouipmen, measuring instruments and iC manufacturing machines.

2.Rotation accuracy:

The spacer retainer fiting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers,the Cross Roller Bearing des not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and ouer rings are designed to be separable, the bearing clearance can be adjusted. in addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.

3.Usage characteristics:

The inner and outer rings, which are separable, are secured to the Cros Roller Bearing body afer the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus,it is easy to handle the rings when installing the Cross Roller Bearing. The spacer retainer keeps rollers in their proper position, thereby preventing them from skewing. This eliminates friction between rollers, and therefore secures a stable rotation torque.the cross array of rollers allows a single Cross Roller Bearing unit to receive loads in all directions, increasing the rigidity to three to four times greater than the conventional type.
