MDC standard rotary motion feedthroughs are a popular and economical solution for in-vacuum sample or device rotation. They are constructed of the highest grade vacuum compatible materials. Position is measured along a 360º laser etched blackanodized barrel graduated in 5º increments. Welded stainless steel bellows, a unique off-axis wobble design and the use of rotary shaft bearing supports provide devices of unsurpassed reliability and performance. Feedthroughs are available on industry standard Conflat®compatible Del-Seal™ CF metal seal flanges or ISO KF Kwik-Flange™ elastomer seal port mounts. Automation can be achieved with one of four motorization options and controls. Motor controls must be purchased separately.
