31309Tapered roller bearings

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 greater the Angle, the greater the axial load capacity. The most used tapered roller bearings are single-row 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 heavy machines such as large cold and hot rolling mills.A single-row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are enclosed by a basket cage into an inner ring assembly, and the outer ring and the inner ring assembly can be separated. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation. Such bearings can only limit the axial displacement of the shaft or housing in one direction and bear the axial load in one direction.
