SFF SS K
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. With the new integrated clamping system, larger bore combinations with high concentricity can be achieved.
- Max. 18‘000 rpm
- High concentric clamp hubs
- Silent at high speed
- High torsional stiffness
- 100 to 1‘000 Nm
