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 type of bearing is that it is capable of supporting high load forces in one direction both radially and axially. Tapered roller bearings are usually 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; it is possible to mount the inner and outer rings independently of each other. Rolling bearings of this type can be divided into three groups based on the contact angle: Normal angle, medium angle and steep angle bearings. In addition, double-row and four-row tapered roller bearings are available. The cages are mainly made of sheet steel. However, plastics such as polyamide, PEEK with and without glass fibre reinforcement can also be used.
