Linear Guided Motion
• High power-to-size ratio
• No bellows, no vacuum thrust
• Position lock facility
• Robust design
• Manual, motorised and pneumatic actuation
Based on the larger Linear PowerProbe 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.
