Definition of tapered roller bearing

The ability of single row tapered roller bearings to bear axial load depends on the contact angle, that is, the angle of the outer ring raceway. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.
