Angular Contact Ball B. SKF 7312 BECBM

The SKF 7312 BECBM single-row angular contact ball bearing with a 60 mm bore accurately accommodates combined radial and axial loads at a 40-degree contact angle.

The 7312 BECBM angular contact ball bearing is a single-row rolling bearing in the SKF Explorer performance class, designed for industrial bearing applications. Thanks to its asymmetrical raceway arrangement, this open bearing transmits axial forces in one direction as well as simultaneously occurring radial forces. The integrated brass cage ensures precise guidance of the rolling elements, which are made from standard 100Cr6 bearing steel. With dimensions of 60 mm inner diameter, 130 mm outer diameter and 31 mm width, this design is suitable for use in a temperature range from -20 to +150 degrees Celsius.

How are axial and radial loads accommodated in the 7312 BECBM angular contact ball bearing?

The bearing is designed for shaft mountings where unilateral axial forces must be supported in combination with radial loads. As a single single-row angular contact ball bearing, by its very design, can only accommodate axial forces in one direction, it is often fitted in pairs in an O or X arrangement. In this configuration, a defined, small amount of axial clearance results, enabling the bearing pair to provide controlled guidance of the supported shaft.

What characteristics do brass cages and tolerance classes P6 and P5 offer?

The BECBM design combines a solid brass cage with tight manufacturing tolerances. Dimensional accuracy to class P6 and running accuracy to class P5 ensure smooth concentricity at higher speeds. The brass cage is suitable for increased thermal loads and contact with more aggressive lubricants. As an open bearing without sealing washers, this design requires a clean installation environment and a lubricant supply via lubricating oil or grease.
