Angular Contact Ball B. SKF 7209 BEP

The SKF 7209 BEP angular contact ball bearing accommodates radial loads as well as high axial loads on one side and has main dimensions of 45 × 85 × 19 mm.

The 7209 BEP angular contact ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) with a standard radial clearance. Thanks to the raceways of the inner and outer rings being offset at an angle to one another, the bearing specifically accommodates combined loads at a contact angle of 40 degrees. The open design without sealing washers allows lubricants to pass freely through the housing, but requires a clean installation environment.

In which installation situations is the 7209 BEP angular contact ball bearing used?

This rolling bearing is used where radial forces coincide with axial loads acting from one side. As single-row angular contact ball bearings, by design, can only accommodate axial loads in one direction, in practice they are predominantly mounted in pairs or in conjunction with a second rolling bearing. This arrangement supports alternating or forces acting from both sides and provides the necessary guidance for the rotating shaft during operation.

What advantages do the 40-degree contact angle and the polyamide cage offer?

The nominal contact angle of 40 degrees gives the bearing arrangement a high axial load-carrying capacity whilst ensuring stable raceway guidance. The BEP version is fitted with a lightweight polyamide cage. This cage material dampens movements, reduces friction on the rolling elements and is designed for operating temperatures between –20 and +120 degrees. The bearing, which has no groove or flange on the outer ring, is manufactured to the standard tolerance class P0/PN (ABEC 1).
