		SINO-R expansion technology from SCHUNK.

		The strengthened extension sleeve increases the radial stiffness associated with high torques. SINO-R is ideal for heavy chip removal.

		Combined with the strengthened extension sleeve, the cover sleeve / clamping sleeve creates maximum torque and in additon prevents dirt/grime intrusion.

		Expansion Chamber with High-End Elastomer

		Clamping Cap The Innovation The new universal toolholder SINO-R is based on the innovative expansion technology with a stiff elastomer as a pressure medium. As the clamping sleeve is tightened axially with the spanner wrench, the elastomer is forced against the expanding sleeve. SINO-R does not require expensive clamping utilities and no determined tightening torques. SINO-R offers highest clamping forces at an unbeatable and easy handling.
