Composite needle roller bearing is composed of a radial needle roller bearing and a thrust bearing, so it can withstand radial and axial loads. The combination needle roller bearing can position the bearing configuration when the radial space is limited. They are particularly suitable for applications where other types of positioning bearings take up too much space or have a large axial load, high speed or insufficient lubrication for only thrust washers.
Needle roller/angular contact ball bearing is a combination of a radial needle roller bearing and a radial angular contact ball bearing, forming a very low cross section of the bearing, can run at high speed, and can bear heavy radial load and light axial load. The radial load is borne entirely by the needle roller/bearing.
