Highest clamping forces with maximum safety

The MCA power clamping nut from JAKOB Antriebstechnik provides the user with a long-proven, widely used and economical clamping element. This clamping technology can guarantee the highest clamping forces and maximum operational safety without any additional installation work - and is very easy to operate manually. All that is required is an SW 17 wrench. However, we recommend using a torque wrench to ensure exact, reproducible clamping forces. The special inner workings, an integrated planetary gear mechanism, multiplies the manual tightening torque.

The power clamping nuts have proven their durability on a specially designed test bench. They were subjected to a continuous load of 10,000 load cycles and were able to confirm all expectations.

The power clamping nut uses stable claws instead of bolts to support the planetary gears, creating space and increasing the power range. The quenched and tempered steel material and the surface coating that protects against corrosion guarantee a long service life for the clamping elements. The MCA mechanical clamping nut is maintenance-free under normal operating conditions and can be used up to 400°C in special versions.

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

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

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