Angular Contact Ball Bearings
Technical Information on Angular Contact Ball Bearings
Last Modified: 15th Apr 2016SKF Angluar Contact Ball Bearings
SKF angular contact ball bearings have race ways in both the inner & outer rings that are displaced in respect to each other in the direction of the bearing axis.
This means SKF angular contact metric ball bearings are designed to accommodate combined loads, i.e. simultaneously acting radial & axial loads.
The axial load carrying capacity of SKF or FAG angular contact ball bearings increases with increasing contact angles.
The contact angle of a angular contact ball bearing is defined as the angle between the line joining the points of contact between the ball bearings & the raceways. In the radial plane, along which the load is transmitted from one raceway to another & a line perpendicular to the bearing axis.

SKF & FAG bearings are both manufactured in wide range of sizes & designs. The angular contact ball bearings most commonly used in engineering are:
- Single row angular contact ball bearings
- Double row angular contact ball bearings
- Four point angular contact ball bearings
- Double row cam rollers
We can also offer a vast range of high precision & high speed angular contact ball bearings from a range of different manufacturers including SKF, SNFA, RHP, NSK & FAG Barden.
