The inner and outer races are expansible and contractable, being made of split rings of austenitic stainless steel. The clamping bolts are made of precipitation hardened stainless steel, and one of the taper rings is provided with a hardened nitrided layer on the surface thereof to be contacted by the clamping surfaces of the clamping bolts.
