Mechanical power clamping nuts May the clamping force be with you

Editor: Alexander Stark

Germany — With its special clamping technology, Enemac wants to address the mechanical engineering industry's demand for ever shorter setup and production times across the board. The mechanical clamping elements type ESB, ESD and ESG generate high clamping forces for a variety of applications.

Expensive special tools are often required to clamp large tools or workpieces. To avoid these acquisition costs, Enemac has developed various mechanical power clamping nuts. These can generate high clamping forces without requiring a great deal of effort or time.

There is a hidden transmission gear in the housing, which can be driven by a small nut outside the housing without great effort. As a result, the internal thread is drawn in slightly, which means that the counterpart is tightened. With this simple principle, a force of 6 to 20 tons can easily be exerted manually.

The power clamping nut only has to be screwed onto the existing bolt, then the operating hexagon at the top can be turned up to the specified torque with a commercially available torque wrench and the clamping nut clamps the workpiece or tool quickly and safely.

Type ESB is intended for workpieces or tools of the same strength, as the screw-in depth is limited by the blind hole. With changing component thicknesses, the ESD series with through hole thread should be used, as this has an unlimited stroke.

The ESG series also has a through hole thread for changing tool and workpiece thicknesses. Their low overall height makes them even more versatile in use.

These mechanical types can be used almost everywhere, e.g. for tensioning conveyor belts, tools in presses and punching or workpieces during welding. Many special versions are available on request, such as high-temperature designs for the foundry sector, or lubrication with food grease for food and laboratory technology.
