Abstract
A locking collar concentric with an inner ring and outer ring of a bearing assembly is advanced axially by threads or other mechanism on an axial extension of the inner ring. A wedge ring provides a wedge between the axial extension and a rotatable shaft upon advancement of the locking collar and grips the shaft. Preferably, conical washers between the axial extension and the locking collar are abutted by the wedge ring to provide further gripping of the shaft upon advancement of the locking collar. The wedge ring may be used alone or in combination with the conical washers to lock the bearing assembly to the shaft.
