Dual Shaft Single Rotary Sample Transporter, for horizontal pincer orientation

Product code: RMD40(H)

The RMD40 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 the 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. All ball bearings are Dicronite (W-disulfide) dry lube coated. On request, the RMD can be built with SiC ceramic hybrid ball bearings.

Pincer grips fitted to the RMD40(H) are oriented horizontally. For vertical orientation of the pincer, see RMD40.
