Angular Contact Ball B. SKF 7228 BM

The SKF 7228 BM angular contact ball bearing, with dimensions of 140 × 250 × 42 mm, can accommodate combined loads with a contact angle of 40 degrees.

The 7228 BM angular contact ball bearing is a single-row rolling bearing designed for demanding industrial applications. Manufactured by SKF, it withstands high radial forces as well as single-sided axial forces. As it is made from standard 100Cr6 rolling-element bearing steel, the component remains dimensionally stable during continuous operation. With an internal diameter of 140 mm, an external diameter of 250 mm and a width of 42 mm, this open bearing is suitable for designs with an external lubrication supply.

What is the 7228 BM angular contact ball bearing suitable for in industrial plant?

The 7228 BM angular contact ball bearing is primarily used where high radial loads occur in conjunction with unilateral axial forces. The contact angle of 40 degrees ensures effective force transmission along the line of contact. Typical applications include industrial shaft bearings with a continuous lubricant supply.

As this is an open bearing, the lubricant can be applied directly to the rolling elements. At the same time, the open design requires a clean installation environment within the housing.

What are the advantages of the brass cage with a 40-degree contact angle?

The solid brass cage guides the rolling elements stably and withstands thermal stresses from –20 to +200 degrees. Brass offers high strength during rapid accelerations or vibrations in the drive system.

When designing your application, please note that this single-row bearing only accommodates axial forces in one direction. For alternating load directions, fit a mating bearing. With tolerance class P0 or ABEC 1, the component fits into standard fit seats with normal tolerances.
