Tapered roller bearings

Tapered roller bearings are designed to accommodate combined loads, that is, radial and axial loads acting simultaneously. The extension lines of the raceway meet at the same point on the bearing axis to achieve true rolling and therefore have low friction torque during operation. The axial load capacity of tapered roller bearing increases with the increase of contact Angle α. The size of the contact Angle (usually 10° to 30°) is related to the calculation factor e (according to the product table) : the larger the value of e, the larger the contact Angle.
