Servoflex SFC DA2
The Double Flex DA2 version of the Servoflex SFC series impresses with its high torsional stiffness including a possible compensation function in axial, parallel and angular direction. Due to the light and high-strength aluminum alloy, it has a low mass inertia.
- Hubs out of high-strength aluminum alloy
- Ultra low inertia
- High torsional stiffness
- High flexibility
- 0.25 bis 250 Nm
