SFS G
The SFS model is a metal-disk coupling with a base made of high-strength steel and double membrane steel plate. A very high torsional stiffness ensures the exact rotation of the shafts for a precise transmission. The SFS G model is available in different lengths.
- Parts delivery possible
- High torsional stiffness
- Variable length available
- Different connection possibilities
- 20 to 800 Nm
