Combined needle roller bearings are considered to be the bearings which include into the design of one product the combination of a radial needle roller bearing and one or two deep groove ball bearings, angular contact ball bearings, thrust (axial) ball bearings, thrust (axial) cylindrical roller bearings or thrust (axial) needle roller bearings. Combined needle roller bearings are used in the units where the space for support location is limited, but in addition to the radial loads the axial loads must be accommodated.
