SFC SA2
The Single Flex SA2 version of the Servoflex SFC series impresses with its extremely high torsional stiffness combined with possible compensation in axial 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
- RoHs compliant
- 0.25 to 250 Nm
