Angular Contact Ball B. SKF 7220 BEP

The SKF 7220 BEP angular contact ball bearing, with dimensions of 100 × 180 × 34 mm and a contact angle of 40 degrees, is specifically designed to accommodate combined loads.

The 7220 BEP angular contact ball bearing is a single-row rolling bearing designed for applications involving combined radial and axial forces. Thanks to the raceways of the inner and outer rings being offset at an angle to one another, this design accommodates unidirectional axial loads together with radial loads. Manufactured from standard roller bearing steel (100Cr6), this version has a bore of 100 mm, an outside diameter of 180 mm and a width of 34 mm. The open bearing is suitable for lubricated systems in industrial drives.

What is the 7220 BEP angular contact ball bearing suitable for?

This rolling bearing is used wherever rotating shafts have to withstand high radial forces and, at the same time, axial forces in one direction. Typical applications include gearbox shafts, pump drives, compressors and general mechanical engineering. As this is an open bearing, it can be integrated directly into oil circuits or into housings sealed on site. For varying axial loads, a second counter-bearing is usually fitted in a matched arrangement.

What are the advantages of the 40-degree contact angle and the polyamide cage?

The 40-degree contact angle determines the line of action of the forces and enables the bearing to accommodate significant axial forces compared to smaller angles. The designation BEP also refers to the optimised internal geometry and the lightweight polyamide cage. This material reduces the cage’s own weight and ensures low-vibration, quiet operation within a temperature range of –20 to +120 degrees. The tolerance class P0/PN or ABEC 1 and standard radial bearing clearance ensure reliable standard installation.
