Long Stroke Air Chucks

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.

Chuck Accuracy

.00005" (0.0012mm) TIR is standard
.00002" (0.0005mm) TIR is available

¹ 2 jaw configurations available for all air chuck sizes, 6 jaw configurations available on 10 inch (250 mm) models ² Chuck accuracy is defined as the total indicator reading (maximum radial and lateral runout) of a master gage measured 1.0" (25 mm) from the face of a standard top jaw ³ Total jaw stroke (on diameter) ⁴ Max. rpm is influenced by air pressure and mass of top jaws
