MDC Port Aligners are adjustable port flange interfaces engineered to compensate for alignment imperfections between vacuum components. These alignment tools eliminate flange stress, improve system integrity, and ensure reliable sample transport, especially in load-lock configurations.

Our specialized Load-lock Gimbal Port Aligners are precision instruments designed for magnetically coupled sample transporters used with both circular and rectangular entry load-lock systems. These units feature micrometer-controlled adjustments for both horizontal tilt (above/below the travel plane) and side-to-side axial displacement, providing a highly refined alignment interface.

Each aligner includes a formed stainless steel bellows adapter, offering both flexibility and vacuum compatibility, and is designed to mount directly between the sample transporter and the staging chamber. MDC also offers a full range of alignment tools including standard gimbals, precision off-axis, and heavy-duty off-axis aligners.

Industry Applications

MDC Port Aligners are essential in semiconductor fabrication, materials research, vacuum metallurgy, and surface science systems. They are ideal for aligning magnetic transporters, beamline optics, and load-lock assemblies, especially where precise alignment reduces component wear and improves operational efficiency. Common in high and ultrahigh vacuum (UHV) environments, these tools enhance mechanical accuracy in mission-critical vacuum setups.
