Magnetically-coupled Linear-Rotary Feedthroughs

The FLLRE series magnetically coupled feedthrough offers exceptional linear-rotary motion for sample introduction and transfer.  The small magnetic driver package provides more than 150 oz-in torque and four lbs of linear force.  The inside traveler has no magnets, but it is made of magnetically permeable material.
