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.
