Design
Draw tube operated design. Can be actuated with either a hydraulic or pneumatic cylinder mounted at the rear of the machine spindle.

Application
OD and ID chucking for cylindrical grinding, turning, and hard turning. Ideal for workpieces requiring high concentricity, and applications requiring high chucking force and/or high spindle speeds.
