Pneumatic Clamping Fasteners

Pneumatic clamping fasteners are designed for quick change applications. Instant pneumatic clamping reduces setup time in multiple-parts holding and frequent changeover of machinery or fixture. This compact pull down clamp is designed to be used with QCPC-series clamping pins. The piston goes up by air supply and the balls move toward the center to pull down the clamping pin. Clamping occurs when air is supplied, and the fasteners unclamp when the air is released. The body is made from 303 stainless steel. Wedge and balls are made from 440C stainless steel, quenched and tempered.
