Tapered roller bearing is a separated type bearing. The inner and outer rings of the bearing have tapered raceways.Single row tapered roller bearings can bear radial load and single direction axial load.When the bearing bears a radial load, an axial component will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.

The capacity of single row conical roller bearing to bear axial load depends on the contact Angle, that is, the outer ring raceway Angle. The larger the Angle, the greater the axial load capacity.Single row tapered roller bearings are the most widely used in tapered roller bearings.Small size double row tapered roller bearings are used in the front wheel hub of the car.Four-row tapered roller bearings are used in large cold and hot rolling mills and other heavy machines.
