Dual Shaft Rotatable Sample Transporter with Slide Bearings DN40CF

Product code: RMJG40-XXXX-YYYY

The RMJG40 is a simple, all metal sealed, linear-rotary feedthrough with independent rotation of the inner as well as the outer shaft. It's main purpose is to transport samples between UHV-chambers. The independent rotary motion of each shaft enhances operation of sample locking mechanisms and sample carrier platforms by being able to drive and also rotate them.
Two sets of rare earth magnets on the air- and vacuumside provide the necessary force to ensure a rigid coupling from the handle to the shaft. Slide bearings for linear motion throughout guarantee for smooth operation even after numerous bakeout cycles.
