Tapered roller bearing
The design of tapered roller bearings is based on the principle of guiding tapered rollers through a guide rib located on the inner ring. One advantage of this bearing type is that it is able to support high load forces in one direction both radially and axially. Tapered roller bearings are generally installed in pairs, making them comparable to single-row angular contact ball bearings. To adjust the bearing clearance, the axial distance between the opposing inner and outer rings is set. Tapered roller bearings can be dismantled and the inner and outer rings can be mounted independently of each other. Bearings of this type can be divided into three groups based on the contact angle: Bearings with a normal angle, with a medium angle and with a steep angle. Double-row and four-row tapered roller bearings are also available. The cages are mainly made of sheet steel. However, plastics such as polyamide and PEEK with and without glass fiber reinforcement can also be used.
