Angular Contact Ball B. SKF 7309 BEP

The SKF 7309 BEP angular contact ball bearing, with dimensions of 45 × 100 × 25 mm and a contact angle of 40 degrees, offers high axial load-carrying capacity in one direction.

The 7309 BEP angular contact ball bearing is a single-row radial rolling bearing made from standard bearing steel (100Cr6). Thanks to the defined arrangement of the raceways, this design can accommodate both radial loads and high axial loads in one direction. The SKF bearing has a bore of 45 mm, an outer diameter of 100 mm and a width of 25 mm. As an open component without integrated seals, it can be flexibly integrated into existing lubrication systems.

In which installation situations does the 7309 BEP angular contact ball bearing accommodate combined loads?

This rolling bearing is used for combined loads with a significant axial component in one direction. As a single angular contact ball bearing can only accommodate axial forces from one side, it is usually paired with a second bearing during operation. This design is suitable for operating temperatures ranging from -20 to +120 degrees and, thanks to its 40-degree contact angle, provides a rigid mounting for rotating machine components.

What is the function of the polyamide cage in the 7309 BEP angular contact ball bearing?

The designator ‘P’ in the suffix ‘BEP’ indicates a polyamide cage, which keeps the rolling elements at a uniform distance apart. This material reduces the bearing’s own weight and promotes smooth running. When designing the application, ensure that the permissible temperature range of -20 to +120 degrees is observed to avoid thermal overload of the cage material. As this is an open bearing, external lubrication with a suitable lubricant supports reliable operation.
