Advantages ofSmaller cylinders allow for more compact fixtures.

Smaller Footprint

Exerts approximately 3 times higher clamping force
than the same size comparison cylinder.

Optimum clamping force does not distort workpieceand holding force is strong enough to withstandmachining loads, allowing for high quality machining.

Distortion!!

General Clamp :High-Power Clamp ：The workpiece is distorted

Clamping force is lowered, yet

due to strong clamping force.

the workpiece is supported by holding force.

Cost Reduction

The initial cost of high-power pneumatic system ismuch less than that of hydraulic system.
The running cost is also reduced with less maintenance.
