Tapered roller bearings can be separated, and the components and outer rings made of inner ring, roller and cage can be installed separately. The contact line modified at the contact between roller and raceway can reduce stress concentration. Tapered roller bearings can withstand large radial loads and axial loads. As the tapered roller bearings can only transmit unidirectional axial loads, another conical roller bearing with symmetrical installation is needed to transmit the axial load in the opposite direction.
Tapered roller bearings with the largest amount of consumption are single row tapered roller bearings. In the front wheel hub of cars, small row double row tapered roller bearings have been used in recent years. Four row tapered roller bearings are used in heavy duty machines such as large cold and hot rolling mills.
Tapered roller bearings mainly bear radial and axial combined loads. Bearing capacity depends on the raceway angle of the outer race, the greater the angle, the greater the load capacity. The bearings are separable bearings. According to the number of rollers in bearings, they are divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance needs the user to adjust when installation; double row and four row tapered roller bearing clearance has been given at the end of the product in accordance with the user requirements, without the user adjustment.
