Tapered Bearings

Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers as rolling elements. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the radial and axial combined load based on the radial load, and is often used in pairs, installed in reverse, the inner and outer seat rings can be installed separately, and the radial and axial clearance can be adjusted in installation and use; The large cone angle mainly bears the axial and radial combined load based on the axial load, and is generally not used alone to bear the pure axial load, and can be used to bear the pure radial load when it is used as a pair configuration (the end of the same name is relatively installed). The ability of a single row tapered roller bearing to withstand an axial load depends on the contact angle, i.e. the outer ring raceway angle, the greater the angle, the greater the axial load capacity. The most widely used tapered roller bearing is a single row tapered roller bearing. In the front wheel hub of the car, small double row tapered roller bearings are used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills
