Dual Shaft Single Rotary Sample Transporter

Product code: RMJ40-XXXX-YYYY

The RMJ40 is an all metal sealed, linear-rotary feedthrough with independent rotation of the inner shaft. It's main purpose is to transport samples between UHV-chambers. The independent rotary motion can be used to operate a sample locking mechanism or to rotate a sample carrier platform. The square shaft makes this feedthrough especially sturdy. A set of rare earth magnets on the air- and vacuumside provides the necessary force to ensure a rigid coupling from the handle to the shaft. It's main bearings are of the sliding type, which ensures durability and smooth operation, even over the course of numerous bake out cycles.

Pincer grips fitted to the RMJ40 are oriented vertically. For horizontal orientation of the pincer, see RMJ40(H).
