Angular Contact Ball B. SKF 7313 BECBP

The SKF 7313 BECBP angular contact ball bearing combines a 40-degree contact angle with precise tolerances for combined loads on a 65 mm shaft diameter.

The 7313 BECBP angular contact ball bearing is designed as a single-row radial rolling bearing to accommodate combined forces. Thanks to its integrated 40-degree contact angle, this design can simultaneously accommodate radial loads and single-sided axial loads. Manufactured from standard rolling-element bearing steel (100Cr6) in SKF’s Explorer design, the unit features P6 dimensional accuracy and enhanced running accuracy to Class P5. The open design allows for direct integration into existing lubrication systems.

What is the 7313 BECBP angular contact ball bearing suitable for in operation?

Design engineers primarily use the bearing in bearing arrangements where high axial forces act in one direction on the rotating shaft. As a single angular contact ball bearing can only accommodate axial forces from one side, it is often fitted as a matched pair. When arranged in pairs in an O or X configuration, this design has a low axial clearance ex works. Typical applications include mechanical bearing arrangements and rotating units with defined guidance requirements.

What advantages do the polyamide cage and the manufacturing tolerances offer?

The lightweight polyamide cage guides the balls with low friction and ensures smooth running within the permissible temperature range of –20 to +120 degrees Celsius. The combination of P6 dimensional tolerance and P5 running tolerance ensures precise concentricity during operation. As this is an open design without integrated sealing washers, the bearing location requires effective housing sealing against the ingress of contaminants as well as a continuous supply of lubricant.
