MD100H Hollow MagiDrive Rotary Feedthrough
Features
- Hollow drive
- 65 mm clear bore
- Powerful, stiff coupling
- No bellows or dynamic seals
- Bakeable to 250°C
- Zero-backlash under low load
The MD100H is selected for demanding high torque and stiffness applications, such as indexing robots or rotating large loads. The MD100H has the largest clear bore in the range and a rear rotatable flange. This enables a component to pass through the center such as UHV Design's cold lance, or a second MagiDrive rotary feedthrough.
