MD40 (CF40, 2.75in OD) MagiDrive Series Magnetically Coupled Rotary Motion Feedthroughs
Features
- True UHV performance
- Magnetically-coupled fail-safe design
- High torque rotation (9Nm)
- No bellows or dynamic seals
- Bakeable to 250°C
- Zero-backlash under low load
The MD40 MagiDrive provides the highest torque, within the range, on a 70 mm OD (2.75" OD CF) flange. The drive is ideally suited to applications such as the rotation of samples and small platens, where stability is key. The MD40 is also available in a hollow configuration.
