Power clamping nut
Flexible application with different clamping heights
With the MDR series, Jakob Antriebstechnik has a universally applicable power clamping nut with a side-mounted operating hexagon and through-hole thread in its range.
The MDR series complements the two clamping nut types MCA and MDA with top operation, which have proven themselves for many years in a wide range of applications. A brand new addition to the range is size 150 with a nominal clamping force of 150 kN.
The key design feature of the MDR clamping nut is a special crown gear with right-angled deflection of the rotation to multiply the tightening torque. The clamping force is built up safely and in a controlled manner in proportion to the tightening torque. This ensures high clamping forces with maximum operational safety with very simple manual operation. With thread size M30, for example, the heavy SW46 wrench usually required is replaced by the SW14 operating hexagon, making work much easier.
In conjunction with variable-length T-slot screws or clamping bolts, the through-hole thread enables very flexible use with different clamping heights or tool thicknesses. In addition to the robust material design, the compact dimensions and especially the very low overall height should be emphasized. This also enables use in extremely confined installation conditions. The MDR clamping nut is maintenance-free under normal operating conditions and can be used in special versions up to 400 °C.
Two sizes are available with a nominal clamping force of 120 kN or 150 kN and thread sizes from M16 to M42.
