7311 ACCBM, Single row angular contact ball bearing, Bore diameter: 55.0 mm; Outside diameter: 120.0 mm; Width: 29.0 mm; Contact angle: 25°; ;.
SKF 7311 ACCBM, These single row angular contact ball bearings, with 25° contact angle, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They have Normal axial internal clearance and are suitable for universal matching, where two bearings can be arranged back-to-back or face-to-face. They have a ball-centred brass cage. They can operate at 20% higher speeds than equivalent bearings with 40° contact angle.
