Precision Magnetic Manipulator (PMM) with Rotary-Only Motion

Rotary-Only Precision Magnetic Manipulators are a versatile and reliable method of introducing rotary motion into a sealed chamber. The Model DBROM handles a high breakaway torque and a tight angular compliance and are bakeable to 250°C. User-specified choices include the size and number of shafts; choice of shaft material; length of shaft; choice of hollow or solid shaft; and end details such as flats, threads, etc. making these units fit a wide range of needs.

Rotary-Only Model DBROP is available with polymer bushings in the magnet carriage riding on the outer tube (outside of vacuum) and are used for simple, manual rotation applications. Model DBROM are typically motor driven and has steel bearings in the magnet carriage.

The innovative design of these Rotary-Only PMMs incorporate all welded stainless steel tubing to avoid wear-related leaks, outgassing of residual oils and burping as well as provide an extremely reliable vacuum and gas seal.
