Standard Magnetically-coupled Linear Drive

Standard Magnetically-coupled Linear Drive

MPPL Series

The MPPL provides internally-guided linear motion of the vacuum shaft, guaranteeing rotation-free motion. Furthermore, the high axial thrust coupling produces no torque and so external rotation of the thimble does not apply a rotational force internally, ensuring smooth motion.

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, incorporated within traditional push pull 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, resulting in smooth, free-moving operation.
