QCK Series Rotary Clamp Cylinder – Double Acting Pneumatic Swing Clamp (12–63mm Bore)

Specification QCK Series Rotary clamp cylinder:The QCK Series rotary clamp cylinder is a double-acting pneumatic clamp combining rotary and linear motion, designed for industrial automation, welding fixtures, and CNC systems. Its compact structure ensures efficient, precise, and safe clamping operations in limited spaces.

Product concept

A rotary clamp cylinder performs a 90° swing motion before clamping, preventing interference with the workpiece during loading. The QCK Series operates using a push-and-turn mechanism, making it ideal for tight installation environments.
