Dual Shaft Sample Transporter with Rotation Stop

Product code: RMDG40(RS)-XXXX-YYYY

The RMDG40(RS) is an all metal sealed, linear-rotary feedthrough with independent rotation of the inner as well as the outer shaft with rotation stop option. This option limits the rotational movement of the rear magnet and thereby prevents mounted mechanical elements like pincer grips from being overloaded and damaged.
The main purpose of the RMDG40(RS) is to transport samples between UHV-chambers. The independent rotary motion of each shaft enhances operation of pincer grips 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. All ball bearings are DicroniteTM (W-disulfide) dry lube coated. On request, the RMDG can be built with SiC ceramic hybrid ball bearings.
