Angular contact ball bearings – the fastest bearings currently in use

When it comes to your product or design, angular contact ball bearings are the best option you have. This word might be quite unfamiliar to you so let me tell you certain types of bearings are particularly designed to support the thrust and radial loads simultaneously. They are ideally suitable for a wide range of applications including gearboxes, electric motors, pumps, clutches, and other high-speed machine tool spindles.

These efficient bearings are important in machinery where reliability, fast rotational speed, and heavy use is required. In angular contact ball bearings, the line of action of the entire load comes in contact between balls and raceways for the formation of the angle with the bearing axis. Both the inner and outer rings are offset to each other. One bearing is usually arranged in a manner so that it can be adjusted against a second bearing.

Usually, these bearings are fitted in pairs – face to face, tandem and back to back.

Back to the back arrangement: It accommodates the radial and axial loads in either direction. Since it has a large distance between the acting load center of the bearing, it can withstand a large force capacity.

Tandem arrangement: It accommodates radial loads and single direction axial loads. Here axial loads are received by both the bearings and thus it can control heavy axial loads.

Face to face arrangement: It accommodates radial loads and axial loads in either direction. It has a smaller distance between the acting load center of the bearing and hence it can withstand a smaller momentary force load capacity. It’s most commonly used where a high level of misalignment angle is required.

The life of angular contact ball bearings is influenced by the tightness or slackness to which the bearings are originally set.
