Pneumatic clamp

Components: Rotary distributors, clamps

All machine tools provide access to the pneumatic systems. Thanks to our specially developed operating principle, our pneumatic clamps boast friction torques that are virtually identical to those of hydraulic clamps.

Subdevices with 6 bar pneumatic clamping can be used in any application with a compressed air supply, making them the number-one choice for customers looking for an easy and clean retrofit solution.

Actuation with 6 bar pneumatics
Pneumatics are comparatively clean and easy to use
Quick and easy retrofitting possible in any machine
Axial acting, meaning low tangential distortion
High frictional torque increases the accuracy of the workpieces
Fast response time means it can be used as a safety clamp
Low axial stroke – low volume flow required
Lots of sizes available to suit every application
Extremely fail-safe, low maintenance and durable thanks to precise matching of materials

The product shown depicts the customer-specific design. Modifications to the shown product are possible and can be requested from us very easily. We would be delighted to give you advice and find a suitable solution together with you.
