Clamping nut with torque limiter

The MCA and MCG power clamping nuts from JAKOB Antriebstechnik are tried and tested clamping devices in production. Until now, the desired nominal clamping force was set precisely by the user using a torque wrench. This is a sensible method for varying clamping forces, allowing the clamping nut to be used flexibly. However, if the same, constant nominal clamping force is always applied, time can be saved and safety increased.

The MCA-DB and MCG-DB variants add a preset torque limiter to the power clamping nuts. This means that a torque wrench is no longer required, a simple wrench is sufficient and the clamping force of the nut is always applied correctly. The torque limiter is installed in an attachment that is preset to the required torque by JAKOB at the factory.

The MCA-DB and MCG-DB series cover nominal clamping forces from 60 to 200 kN. It is also possible to have the manufacturer add the integrated torque limiter to existing power clamping nuts from the underlying MCA and MCG series.
