Purpose of Tapered Roller Bearings
Tapered roller bearings are bearings that
can take both axial loads (sideways or thrust forces), as well
as radial loads (downward force). Looking at the diagram below,
the bearing angle determines how much axial and radial load
the bearing can sustain.
Looking at the diagram below, the inner and outer ring raceways
are segments that are made with a taper. This is done so that
the conical surfaces of the raceways and the roller axes if
projected, will all meet at a common point, or apex, on the
main axis of the bearing.
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 Diagram of Tapered
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.
