Their durability has been proven on a specially designed test bench. They were subjected to a continuous load of 10,000 load changes and were able to confirm all expectations.

The power clamping nut supports the planetary gears with stable claws instead of bolts, which creates space and increases the power range. The material made of heat-treated steel and the surface coating that protects against corrosion guarantee a long service life for the clamping elements. The mechanical clamping nut MCA is maintenance-free under normal operating conditions and can be used in a special version up to 400 ° C.

The power clamping nuts are used in all areas of mechanical engineering where large clamping forces are required. For example, the economic clamping of press and punching tools or workpiece clamping during machining. But also in steel and jig construction there are universal application areas.

The series MCA is available with clamping screws from M12 to M64 and with clamping forces up to 200 KN in the standard program.

Variants

In the MCA-S/MCA-T version, the power clamping nuts have been expanded to include a star or T-handle to enable easy manual operation.

The latest MCA-DB series already has an integrated torque limiter. This means that no torque wrench is required and overloading of the clamping nut is effectively prevented.
