30224 Tapered roller bearing

Tapping machine bearing have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
The capacity of single-row tapered roller bearings to bear axial load depends on the contact Angle, that is, the outer raceway Angle, the greater the Angle, the greater the axial load capacity. Single row tapered roller bearings are the most widely used tapered roller bearings. Small size double row tapered roller bearings are used in front wheel hub of car. Four row tapered roller bearings are used in heavy machines such as large cold rolling mill and hot rolling mill.
