The presser ( 7, 107 ) for the axial pre-loading of the internal crowns ( 4 ) of the bearings, is co-axially inserted in the driver ( 9 ), with possibility of relative movement with respect to the same driver. The internal crown of the bearing which is resting on the flat reference surface ( 106 ) co-operates with a centring pin ( 306 ) which may be provided with movable and active members ( 10 ) useful for the same centring. |
