Hydraulic clamp

Components: Rotary distributors, clamps

Our highly responsive, patented axial active clamp is spring-preloaded and is ideal for use as a safety clamp in horizontal axis configurations. The material combination is designed to ensure a long service life, minimise maintenance costs and reduce downtime.

Actuation with 60 bar hydraulics
The simple design is possible in all sub-assemblies
Axial acting, meaning low tangential distortion
High frictional torque increases the accuracy of the workpieces
The optimal design reliably dissipates the machining forces
the additional damping helps to produce perfect machining results
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.
