Angular Contact Ball B. SKF 7048 BGM

The SKF 7048 BGM single-row angular contact ball bearing, with a 240 mm bore and a brass cage, provides a robust guide for combined radial and axial loads.

The 7048 BGM angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 240 x 360 x 56 mm. In this standard open design, without a flange or groove on the outer ring, the bearing accommodates radial loads as well as single-sided axial forces. Thanks to its manufacture to tolerance class P0 (ABEC 1) and standard radial clearance, the component fits precisely into large-scale industrial bearing arrangements.

What are the applications of the 7048 BGM angular contact ball bearing in mechanical engineering?

The angular contact ball bearing is used where large-diameter shafts need to be guided and axial forces absorbed in a defined direction. Typical applications can be found in general mechanical and plant engineering, in gearbox stages and in industrial powertrains. As the design only accommodates axial forces in one direction, it is often fitted in combination with a second bearing positioned opposite to it, in order to absorb axial forces on both sides.

What are the functions of the contact angle and the brass cage in the 7048 BGM?

The nominal contact angle of 40 degrees determines the force transmission from the raceways to the rolling elements and enables high axial forces to be absorbed. A brass cage guides the row of balls. This open-type component is suitable for a temperature range of –20 to +200 degrees. As no sealing washers are fitted as standard, designers select the lubricant and the external housing seal to suit the specific operating environment.
