Angular contact bearings have one ring shoulder removed, either from the inner or outer ring. This allows a larger ball complement than is found in comparable deep groove bearings, giving a greater load capacity. Speed capacity is also greater. Barden angular contact bearings have a nominal contact angle ranging from 10° to 25°. they can be used in pre-loaded duplex sets, back to back (DB), face to face (DF) for supporting thrust loads in both directions, or in tandem (DT) for additional capacity. Angular contact bearings support thrust loads or combinations of radial and thrust loading. They cannot accept radial loads alone. A single angular contact bearing can be loaded in one thrust direction only, this may be an operating load or pre-load. Separable and non-separable types are both available. Separable bearings are useful where bearings must be installed in blind holes or where press fits are required on the shaft and in the housing. The separable feature also permits dynamic balancing of the rotating components with the inner ring mounted in place without the outer ring and housing.
