Standard Magnetically-coupled Linear Drive
Our MPPL Series
The MPPL provides internally-guided linear motion of the vacuum shaft, guaranteeing rotation-free movement. Furthermore, the high axial thrust coupling produces no torque. External rotation of the thimble doesn’t apply a rotational force internally either. This ensures the smoothest motion possible.

How it works
The range can be actuated manually, pneumatically or motorised with DC or stepper motors. Additionally, switches can be provided to prevent over-travel and to aid system interlocks.
The MPPL provides a simple and intrinsically safe alternative to bellows push-pull systems. Utilising UHV Design’s magnetic coupling technology, the magnetic push-pull removes the need for edge-welded bellows stacks that are incorporated within traditional designs. Their elimination maximises vacuum integrity, providing a robust, cost-effective solution. Also, unlike a bellows-sealed device, the MPPL is not subject to the thrust due to vacuum. This results in a smooth, free-moving operation.
