SKF 33109/Q, Single row tapered roller bearing, 45 mm ID, 80 mm cup OD, 27.28 mm WD

ISO class single row tapered roller bearings are designed to accommodate axial loads acting in one direction only. Under radial loads an axial force is produced in the bearing which must be counteracted. Therefore it is customary for single row taper roller bearings to be adjusted against a second taper roller bearing.
