Definition of tapered roller bearings
- Aug 01, 2017 -

Tapered roller bearings are separate type bearings with tapered raceways in the inner and outer rings of the bearings. The type of bearing is divided into single row, double row and four row tapered roller bearing according to the number of columns of the roller. Single row tapered roller bearing can withstand radial load and single direction axial load. When the bearing is subjected to a radial load, an axial force will be produced, so that another bearing that can withstand the axial thrust of the reverse direction is needed to balance it.

The ability of single row tapered roller bearings to withstand axial loads depends on the contact angle, that is, the raceway angle of the outer ring, the larger the angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearings. In the front wheel hub of the sedan, a small size double row tapered roller bearing is used. Four row tapered roller bearings are used in heavy-duty machines such as large-scale cold and hot-rolled machines.
