MDC standard rotary motion feedthroughs are a cost-effective and reliable solution for in-vacuum sample or device rotation. Designed with high-grade vacuum-compatible materials, these devices feature 360° laser-etched black anodized barrels, graduated in 5° increments for clear and accurate positioning.

Each unit includes a welded stainless steel bellows with a unique off-axis wobble design and rotary shaft bearing supports, offering exceptional stability and performance in vacuum applications. Available in both ultrahigh vacuum (UHV) and high vacuum (HV) configurations, MDC feedthroughs are offered with Conflat® CF metal seal flanges or Kwik-Flange™ ISO KF elastomer seal mounts for easy integration.

Manual operation is standard, and motorization is available with four drive options (controls sold separately) for automated in-vacuum rotation.

Industry Applications

MDC’s standard rotary motion feedthroughs are widely used in semiconductor processing, surface analysis, materials science, vacuum instrumentation, and sample manipulation systems. Their robust construction and precision rotary control make them ideal for manual or automated rotational positioning, such as in wafer handling, shutter actuation, and probe alignment within HV or UHV chambers.
