Angular Contact Ball B. SKF 7312 BEP

The SKF 7312 BEP angular contact ball bearing, with a 60 mm bore and a 40-degree contact angle, provides a robust bearing solution for unilateral axial and radial forces.

The 7312 BEP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 60x130x31 mm. Thanks to the asymmetrical shoulders on the inner and outer rings, this design specifically accommodates radial forces as well as unidirectional axial forces. SKF manufactures this model in tolerance class P0/PN (ABEC 1) with standard radial clearance. This open component is suitable for oil- or grease-lubricated assemblies in mechanical engineering and can withstand operating temperatures ranging from –20 to +120 degrees.

In which mounting situations is the 7312 BEP angular contact ball bearing used?

The 7312 BEP angular contact ball bearing is primarily used when high radial loads, together with unilateral axial forces, act on the shaft. Thanks to its contact angle of 40 degrees, the bearing effectively transfers axial thrust forces to the surrounding structure. This design is suitable for assemblies subject to combined loads.

Typical applications include shaft mountings where defined guiding forces in one direction are required. As this is a standard design without ring grooves, the component can be fitted precisely into cylindrical housings. For alternating axial directions, it is combined with a second angular contact ball bearing mounted in the opposite direction.

What are the key features of the BEP design with a polyamide cage?

The polyamide cage in the BEP design guides the rolling elements with low friction and keeps the weight of the rotating component low. This cage material supports low-vibration operation within the permissible temperature range of -20 to +120 degrees. This design combines thermal load-bearing capacity with good running characteristics.

The open design must be taken into account during design: the bearing has no integrated seals. Consequently, its use requires external sealing of the bearing housing as well as lubrication with oil or grease. The standard tolerance class P0/PN (ABEC 1) facilitates replacement during maintenance work.
