7308 BECBM, Single row angular contact ball bearing, Bore diameter: 40.0 mm; Outside diameter: 90.0 mm; Width: 23.0 mm; Contact angle: 40°; Class P6 (P6);.

SKF 7308 BECBM, These single row angular contact ball bearings can accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They can operate at high speeds and, depending on the variant, even very high speeds. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.
