Tapered roller bearings are separable bearings, bearing inner and outer rings with tapered raceways line. These bearings are mounted on roller rows into single row, variable row and four-row tapered roller bearings, such as different structural types. Single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load, will produce an axial force component, so when you need another axial force can withstand the opposite direction of the bearing to be balanced.
Single row tapered roller bearing axial load capacity depends on the contact angle, ie the outer ring raceway angle, the greater the angle, the greater the axial load capacity. Tapered roller bearings is the largest amount of single row tapered roller bearings. In the car's front wheel hub, spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill and other heavy machines.
