Needle roller bearings are combined needle roller bearings where the needle roller bearing works as radial and the ball bearing as thrust. The ball bearing is used either as a single or double direction angular contact bearing or as a thrust bearing. These bearings are used when there are high revolutions, high radial loads occur and low axial loads occur while the space is limited. Needle roller bearings combined with a ball bearing are usually mounted without an inner ring, because with direct bearing on a hardened journal, higher running accuracy and a smaller lateral play spread can be achieved.

Needle roller bearings are needle roller bearings combined with a cylindrical roller bearing. A needle bearing works as a radial bearing and a cylindrical roller bearing as a thrust bearing. The cylindrical roller bearing is either used as a single or double direction angular contact bearing or as a thrust bearing. They are used in cases where, with a small space for bearings, high rotations occur and, in addition to high radial loads, there are also low axial loads. Needle roller bearings combined with a cylindrical roller bearing are usually mounted without an inner ring, because with direct bearing on a hardened journal, higher running accuracy and a smaller lateral play scattering can be achieved.
