Crossed Roller Bearings

Crossed roller bearings have the rollers placed axially perpendicular to each other alternately and therefore are called crossed roller bearings. The rollers are sparated by disc shaped spacers instead of a traditional retaining cage. Either the inner ring or the outer ring is split and held together by retaining rings and the corresponding outer ring or inner ring is one piece. These bearings are therefore separable.

Crossed roller bearings can carry high radial loads, high axial loads in either direction, as well as moment loads. These bearings also have high rigidity and high running accuracies.


AEC crossed roller bearings are available in the following design variants:
