Taper Roller Bearing Description

Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.

Taper Roller Bearings Applications

The conical geometry in the bearing uses line contact, which permits greater loads to be carried than with a point contact (ball) bearing. The rollers are guided by a flange on the back of the inner ring (See Components of a Tapered Roller Bearing). This stops the rollers from sliding out at high speed due to their momentum. The larger the half angles of these cones, the greater the axial load the bearing can sustain.

In wheel bearing applications, both radial and axial loads are present. The weight of the vehicle creates the downward load, which is the radial load. The axial load, or thrust load, is created by the turning of the vehicle.
