7308 BE-2RZP, Single row angular contact ball bearing, Bore diameter: 40.0 mm; Outside diameter: 90.0 mm; Width: 23.0 mm; Contact angle: 40°; Normal;.

SKF 7308 BE-2RZP, These single row angular contact ball bearings, with 40° contact angle and non-contact seals on both sides, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They have a ball-centred glass-fibre reinforced PA66 cage. They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.
