Angular Contact Ball B. SKF 7313 BEP

SKF single-row angular contact ball bearing 7313 BEP with a 65 mm bore, 140 mm outer diameter and a 40-degree contact angle for combined radial and axial loads.

The SKF 7313 BEP angular contact ball bearing is a single-row radial rolling bearing made from standard bearing steel (100Cr6) with standard radial clearance. Thanks to the diagonally opposed raceways of the inner and outer rings, this design accommodates axial forces in one direction as well as radial loads simultaneously. The open bearing features a polyamide cage for precise guidance of the rolling elements and operates within a temperature range of -20 to +120 degrees Celsius.

What load configurations can the 7313 BEP angular contact ball bearing accommodate?

Single-row angular contact ball bearings simultaneously accommodate radial forces and unidirectional axial forces. To accommodate opposing axial forces, this design usually requires a second bearing mounted in a mirror-image configuration. This design is used in shaft bearings subjected to combined loads. As it is manufactured to tolerance class P0 (ABEC 1), the unit can be integrated into standardised housing seats.

What is the function of the 40-degree contact angle and the polyamide cage?

The 40-degree contact angle ensures that the force is transmitted at a steep angle to the radial plane. As a result, the component can withstand higher unidirectional axial forces than bearings with a smaller contact angle. The integrated polyamide cage is characterised by its low weight and damping properties, which promote smooth running. In the open version without sealing washers, the type of lubricant and housing seal can be tailored to the specific operating conditions.
