Rotary Feedthroughs – Bellows Sealed

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.
