Combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing and are consequently able to take up both radial and axial loads. Combined needle roller bearings provide the means to produce locating bearing arrangements in a minimum of radial space. They are particularly useful where the axial loads are too heavy, speeds too high, or lubrication inadequate for simple thrust washers to be suitable, and other types of locating bearing take up too much room.

SKF combined needle roller bearings are available in the following designs:

– Needle roller/angular contact ball bearings (fig 1).

– Needle roller/thrust ball bearings (fig 2).

– Needle roller/cylindrical roller thrust bearings (fig 3).
