Long stroke air chucks feature extended jaw opening for load clearance or to clamp a range of diameters without changing top jaws. Long stroke chucks are available in rotating and stationary configurations. Their high accuracy makes them ideal for clamping headed workpieces for turning, grinding, or milling/drilling applications. Special models with total jaw stroke of .500" (12.7mm), .750" (19.1mm), and 1.000" (24.5mm) are also available. Please call for information.
