Pneumatic Locking Swing Clamps

Power Workholding

Product Information

KOSMEK Pneumatic Locking Swing Clamps are high-power pneumatic swing clamps with a built-in mechanical lock, designed to replace hydraulic clamping in fixture applications. A boosting piston multiplies clamping force to approximately three times that of a same-size conventional pneumatic swing clamp (WHA), enabling heavy-load and high-precision machining without the need for a hydraulic power pack or associated piping. The mechanical locking system provides holding force approximately three times clamping force, resisting machining thrust and reaction forces while minimizing work distortion by keeping clamping force at the necessary minimum.

The WHE delivers equivalent clamping force two sizes smaller than the conventional WHA model. Compact below-flange dimensions are maintained even with the integrated mechanical lock. A three-line lead groove and outer race ball guide swing mechanism provides high-speed, high-durability arm rotation. A purpose-built dust seal with chemically resistant sealing material protects against high-pressure coolant, including chlorine-based formulations.

WHE Pneumatic Swing Clamps are available in right swing (2GR) and left swing (2GL) configurations across four body sizes at 0.5 MPa operating pressure: Size 100 (0.98 kN clamping / 2 kN holding), Size 160 (1.57 kN / 3 kN), Size 250 (2.44 kN / 5 kN), and Size 400 (3.86 kN / 8 kN). Addittional sizes and variants are available. Made in Japan.
