Servoflex SFC DA2 C
The Double Flex DA2 version of the Servoflex SFC series is a clean room compatible product that has been cleaned, assembled (ISO class 6) and packed in consideration of its use in clean rooms. It 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
- Clean room suitable surface treatment (ISO class 6)
- Ultra low inertia
- High torsional stiffness
- 5 to 100 Nm
