Angular Contact Ball B. SKF 7308 BECBJ

The SKF 7308 BECBJ single-row angular contact ball bearing with a 40 mm bore accommodates combined radial and axial loads at a contact angle of 40 degrees.

The 7308 BECBJ angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 40 mm inner diameter, 90 mm outer diameter and 23 mm width. The manufacturer, SKF, produces this version with a sheet steel cage and standard radial clearance. Thanks to its open design, with no flange or groove on the outer ring, the bearing can be lubricated via the housing structure. The component is designed for a temperature range of –20 to +150 degrees.

What loads does the 7308 BECBJ angular contact ball bearing accommodate during operation?

The 7308 BECBJ angular contact ball bearing simultaneously withstands radial loads and unidirectional axial forces. Thanks to its contact angle of 40 degrees, the bearing effectively transfers axial loads into the raceways. Typical applications include shaft mountings subject to combined loads. Its classification in tolerance class P0/PN or ABEC 1 ensures smooth running in industrial applications.

What distinguishes the BECBJ design when arranged in a bearing pair?

The designation refers to key design features: the letter B stands for the 40-degree contact angle, whilst the design is intended for installation in pairs. When two bearings are mounted in an O or X arrangement, a defined, low axial clearance is created as a result of the design. The integrated sheet steel cage guides the rolling elements within a temperature range of -20 to +150 degrees. As this is an open bearing, users select the lubricant and external seal to suit the specific installation environment.
