Bellows Sealed Rotary Feedthroughs (CF)
Accu-Glass Products high-torque HTR series rotary CF feedthroughs are designed to operate at temperatures as high as 250°C and rotational torque up to 250 in-oz. They are constructed of black-anodized aluminum and stainless steel, where only stainless steel surfaces are exposed to the vacuum environment. In vacuum bearings are dry-film lubricated with tungsten-disulfide, while airside bearings are lubricated with high-temperature Krytox® lubricant. The rotation shaft is sealed with an AM-350 edge-welded bellows.
Standard rotary CF feedthroughs are fitted with a 1.65 diameter manual actuator, which can be fitted with an optional three-spoke Speed-Handle for faster actuation. Factory-converted motorized solutions are also available on request. Our motor options include a reversible constant speed AC motor, two DC stepper motors, for medium and high torque applications respectively, and a 90° pneumatic actuator. Manual feedthrough rotation can be monitored via a 360° / 5° increment laser-etched scale found on the manual actuator knob. Rotary feedthroughs are available on Conflat® compatible CF style metal seal or ISO-KF elastomer seal flanges.
