Angular Contact Ball Bearings

Technical Information on Angular Contact Ball Bearings

SKF 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.

Supplementary Designations

CB	Bearing for universal matching. Two bearings arranged back-to-back or face-to-face will have a Normal axial internal clearance before mounting
CC	Bearing for universal matching. Two bearings arranged back-to-back or face-to-face will have an axial internal clearance greater than Normal (CB) before mounting
DB	Two bearings matched back-to-back
DF	Two bearings matched face-to-face

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.
