Angular Contact Ball B. SKF 7320 BECBP

The SKF 7320 BECBP angular contact ball bearing, with a 100 mm bore and a 40-degree contact angle, accommodates high unilateral axial loads as well as radial forces.

The single-row angular contact ball bearing 7320 BECBP is designed for combined loads. Thanks to the angular arrangement of the raceways relative to one another, this rolling bearing specifically dissipates axial forces in one direction. SKF manufactures this version from standard 100Cr6 rolling bearing steel in the Explorer performance class. With an outer diameter of 215 mm and a width of 47 mm, this open bearing is suitable for designs where an external lubrication supply is provided.

What loads can the 7320 BECBP angular contact ball bearing accommodate?

This bearing is primarily used in bearing arrangements where, in addition to radial forces, significant unilateral axial forces act on the shaft. As a single angular contact ball bearing can only accommodate axial loads in one direction, it is often fitted in pairs with a second bearing. The design is such that a pair of bearings, when mounted in an O or X arrangement, has a defined, low axial clearance. The polyamide cage guides the rolling elements with low vibration.

What do a 40-degree contact angle and tolerance class P6/P5 mean?

The nominal contact angle of 40 degrees determines the force transmission and gives the bearing a considerable axial load-carrying capacity. The specification combines dimensional accuracy in accordance with tolerance class P6 with higher running accuracy in accordance with P5, which promotes smooth concentricity. The component has standard radial clearance and operates within a temperature range of –20 to +120 degrees Celsius. As the bearing is of an open design, the bearing housing requires effective sealing to prevent the ingress of contaminants.
