SFF SS B
The new SFF model in the Single Flex design, revised in 2018, impresses with its compact design and high torsional stiffness. Through the disk pack angular and axial misalignment can be compensated. The specially developed clamping principle achieves a very high concentricity.
- Max. 18‘000 rpm
- High concentric clamping hubs
- Silent at high speed
- High torsional stiffness
- 8 to 600 Nm
