MD35H (CF38, 2.75"OD) Hollow

 

  • Hollow drive
  • 12 mm clear bore
  • Medium torque
  • No bellows or dynamic seals
  • Bakeable to 250°C
  • Zero-backlash under low load

The MD35H is a medium torque, medium stiffness rotary drive. Configured with a hollow body the MD35H has a rear fixed CF16 flange enabling a component to pass through the centre, such as UHV Design’s cold lance, or a second MagiDrive rotary feedthrough.
