MRD93 Magnetic Rotary Drive

Magnetically Coupled UHV Rotary Drive

The MRD93 is a manual magnetic rotary drive which uses high strength Sm2Co17 magnetic coupling to transfer rotational forces into the vacuum envelope. This is achieved without any dynamic seals or bellows making these devices exceptionally robust and no risk of a vacuum leak for the life of the drive. The magnetic coupling ensures the devices are exceptionally robust and cannot be damaged with excessive torque. The drive is fully bakeable to 250°C.
