Due to the X arrangement of the rolling elements, these bearings can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads with a single bearing position. This allows designs with two bearing positions to be reduced to a single bearing position. Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, little clearance or preload. The bearing outer rings can be easily located in the adjacent construction by means of clamping rings.
Split outer ring with mounting holes (CRBD): Consisted of an inner ring and two outersemi-rings with mounting holes. Because there are mounting holes, so it can be fixeddirectly and it is suitable for rotating of inner ring.
