Angular Contact Ball B. SKF 7307 BECBP

The SKF 7307 BECBP angular contact ball bearing, with a 35 mm bore, accommodates radial loads and unilateral axial forces at a contact angle of 40 degrees.

The 7307 BECBP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with dimensions of 35 × 80 × 21 mm. In SKF’s Explorer version, this unit combines dimensional accuracy to tolerance class P6 with running accuracy to P5. Thanks to the polyamide cage, the open bearing operates within a temperature range of –20 to +120 degrees. The design is optimised to accommodate combined loads consisting of radial forces and single-sided axial loads in mechanical engineering applications.

What is the 7307 BECBP angular contact ball bearing suitable for in operation?

This single-row bearing is suitable for mounting positions subject to combined loads, where radial forces occur alongside high unilateral axial forces. Due to the 40-degree contact angle, this design supports axial forces in one direction. If alternating axial loads occur, the bearing pair can be mounted in an O or X arrangement. In these configurations, the bearing set has low axial clearance, which supports precise shaft guidance under dynamic loads.

What should be borne in mind regarding the open design and lubrication?

As an open roller bearing, this model has no sealing washers. For use in the temperature range from –20 to +120 degrees, an external housing seal to protect against dirt is advisable. Lubrication can be provided either with lubricating oil or grease compatible with the polyamide cage. As the outer ring has no flange or groove, the component fits flush into housing bores. When fitted in pairs, the arrangement relative to a second bearing determines the desired axial play.
