SFF DS B
The new SFF model in the Double Flex design, redesigned in 2018, impresses with its compact design and high torsional stiffness. Due to the double disc pack, angular, parallel as well as axial offsets can be compensated. The specially developed clamping principle achieves highly concentric clamping.
- Max. 14‘000 rpm
- High concentric clamping hubs
- Silent high speed operation
- High torsional stiffness
- 8 bis 600 Nm
