Our range of high torque rotary motion feedthroughs are designed to operate at temperatures as high as 250°C and rotational torque up to 1.766Nm. Feedthroughs are constructed from black anodized aluminium and stainless steel, with only stainless steel faces being exposed to the vacuum environment. In-vacuum bearings are dry-film lubricated with tungsten-disulphide, while air side bearings are lubricated with high-temperature Krytox® lubricant. The rotational shaft is sealed with an AM-350 edge welded bellows.
Features: • All precision bearings. • Improved shaft coupling designed for high torque, rated to 1.766Nm. • High temperature rated to 250°C. • UHV compatible construction. • Welded bellows seal. • Manual actuator. • Continuous rotary motion. • Rotary position lock. • Optional stepper motor or air actuator.
