Sample Transporter with Motorized Linear Drive

Product code: RM40-0500-0030-DRVRMOTL

The RM40-DRVRMOTL is a linear-rotary feedthrough for ultra high vacuum applications, equipped with a stepper motor-driven one axis linear actuator. The motorized spindle drive is coupled to the air side magnet of the RM40 and controls the linear motion of the inner shaft. The sturdy linear unit ensures unchanging alignment of all components and consistent positioning.

Slide bearings guarantee for smooth operation of the sample transporter even after numerous bakeout cycles.

Please note that for bakeout the drive must be removed.
