High-torque Linear/Rotary Feedthrough

Product code: MD40HT-XXXX-YYYY

The high-torque version of the linear/rotary feedthrough doubles up the coupling force. In specific applications, for instance when used as a "screw driver" for engaging a thermal link, a higher force coupling is desirable.

  • Standard stroke: 0100 / 0200 / 0300 / 0400 / 0500mm
  • Standard retracted length: 0030mm
  • Customized stroke: Specify XXXX Min. 50mm / max. 700mm
  • Customized retracted length: Specify YYYY Min. 10mm / max. 250mm

Standard Example: MD40HT-0300-0030 = High-Torque Linear/Rotary Feedthrough DN40CF, 300mm linear travel, retracted shaft length 30mm.

Customized Example: MD40HT-0650-0075 = High-Torque Linear/Rotary Feedthrough DN40CF, 650mm linear travel, retracted shaft length 75mm.

See below for MD40HT compatible options and accessories
