Background

The inner ring and the outer ring of the tapered roller bearing are provided with tapered raceways, and the tapered roller bearing can be divided into single-row, double-row and four-row tapered roller bearings and other different structural types. The single-row tapered roller bearing can bear radial load and single-direction axial load. When the bearing is subjected to a radial load, an axial force component will be generated.

The tapered roller bearing is a radial thrust type rolling bearing in which the rolling elements are tapered rollers. There are both small and large cone angles. The small taper angle mainly bears radial and axial combined loads which mainly take radial loads, the combined loads are frequently used in a double mode and are reversely installed, the inner race and the outer race can be respectively installed, and radial and axial clearances can be adjusted in installation and use; the large taper angle is primarily responsible for combined axial and radial loads dominated by axial loads, and is generally not solely responsible for pure axial loads, but for pure radial loads when in a paired configuration.

The tapered roller bearing mainly bears combined radial and axial loads which are mainly radial. The bearing load capacity depends on the raceway angle of the outer ring, with the greater the angle the greater the load capacity. The bearing belongs to a separated bearing, and is divided into a single-row tapered roller bearing, a double-row tapered roller bearing and a four-row tapered roller bearing according to the row number of rolling elements in the bearing. The play of the single-row tapered roller bearing needs to be adjusted by a user during installation.
