Servoflex SFS W

The SFS-W model is a metal disk coupling with a base made of high-strength steel and double membrane steel plates. A very high torsional stiffness ensures the exact rotation of the shaft and ensures a precise transmission. The assembly is possible via bore with key way or clamping set.

Parts delivery possible
High torsional stiffness
Compensation function
Different adaptions possible
20 to 800 Nm
