Angular Contact Ball B. SKF 7220 BECBM

The SKF 7220 BECBM angular contact ball bearing, with a brass cage and a 100 mm bore, accommodates radial and single-direction axial loads during operation.

The single-row angular contact ball bearing 7220 BECBM is designed as an open rolling bearing for combined loads. Manufactured from standard rolling bearing steel 100Cr6 and available in the Explorer version, the component offers high material quality. Thanks to its dimensions – a bore diameter of 100 mm, an outside diameter of 180 mm and a width of 34 mm – the bearing can be integrated into standardised housings. As an open component without an integrated seal, external lubrication within the unit is required.

What loads is the 7220 BECBM angular contact ball bearing designed to withstand?

This rolling bearing primarily absorbs radial forces together with axial forces in one direction. Thanks to the contact angle of 40 degrees, the design transfers axial loads via the rolling elements. Typical applications include bearing arrangements operating at high speeds and under combined forces. As a single angular contact ball bearing can only support axial forces from one side, it is usually fitted in pairs opposite a second rolling bearing, which acts as a counter-guide.

What are the key features of the cage and design?

The solid brass cage guides the balls with low friction and is suitable for operating temperatures ranging from –20 to +150 degrees Celsius. Manufacture to tolerance class P6 for dimensional accuracy and P5 for running accuracy ensures smooth operation. The component is designed for installation in sets: in an O or X arrangement, a defined, minimal axial clearance is immediately established within the bearing pair. This simplifies assembly without the need for time-consuming shim fitting.
