LinClamp clamping and braking systems are designed to brake and retain masses  moving axially over linear guide rails and elements. Their design, surface quality, and dimensional, shape, and positional tolerances are equivalent to the commercially available linear guide rails.


  • suitable for almost all sizes and manufacturers of linear guide systems as well as for surfaces
  • compact design, suitable for high and low carriages, simple installation
  • easy to install
  • compatible to other rail clamping systems
  • pneumatic clamping or braking of the highest forces
  • optimum safety clamping, failure of pneumatics results in clamping (types S, SK, A)
  • low system costs in comparison to hydraulics and electronic solutions
  • special linings for clamping without loss of holding power for linear guides with grease lubrication.

Operating principles

LinClamp S/SK released Compressed air is applied to the chamber between the two spring steel diaphragms. This deforms the spring steel sheets elastically and shortens them in the horizontal direction. The clamp body is deformed in such a way that it contacts at the top with the spring steel sheets and expands at the bottom around the brake shoes. This lifts the brake shoes from the rail and it can be moved freely.

LinClamp S/SK clamped: The chamber between the two spring steel diaphragms is vented. The spring steel sheets spring back to their normal position and expand the upper part of the clamping body. However, this expansion at the top simultaneously leads to a narrowing at the bottom. This narrowing causes the brake shoes to press against the rail and to clamp it.

LinClamp SA released: Venting causes the sheet to spring back and splays out the clamping body below the slide way. The base plate, which has previously been reformed elastically, now springs back to its starting position. It is thereby narrower above the cross web and wider beneath it. The brake shoes lift off from the rail. Operating pressure 4 to 6 Bar.

LinClamp SA clamped: To activate the clamping mechanism, the chamber below the spring steel sheet is filled with compressed air. The prestressed spring steel sheet is thereby pressed upwards and simultaneously stretched. Simultaneously, the lower part of the clamping body is narrower over the cross web as pivot point. This presses the brake shoes against the rail.
