Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is.
Single-row tapered roller bearings are mainly used in gearboxes, lifting equipment, rolling mills and mining machinery, such as tunnel boring machines. In the front wheel hub of the car, a small size double row tapered roller bearing is used.
