Needle Roller Angular Contact Bearings

In addition to radial forces, needle roller/angular contact ball bearings can support axial forces in one or both directions. Needle roller/angular contact ball bearings capable of supporting axial loads in one direction act as semi-locating bearings, while bearings capable of supporting axial loads in both directions act as semi-locating or locating bearings. Needle roller/angular contact ball bearings comprise a radial needle roller bearing, an angular contact ball bearing as the axial component and an inner ring. In the case of type NKIA the inner ring is of a single-piece design, whereas type NKIB has one narrow and one wide inner ring. The ball cage of the axial bearing component is made from plastic. The bearings have a low radial section height and are suitable for high speeds. As needle roller/angular contact ball bearings are not self-retaining, the inner ring can be mounted independently of the outer ring and the needle roller and ball set. Show details
