Linear Non-guided Motion
• High power-to-size ratio
• No bellows, no vacuum thrust
• Position lock facility
• Robust design
• Manual, motorised and pneumatic actuation options
MPPs provide linear motion of an ‘unguided’ vacuum shaft (free to rotate). This is used to manipulate slides or pivot arms where a guided system may conflict with the mechanism. Please note that although the vacuum shaft is free to rotate the MPP does not provide rotation.
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 MPP range 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 MPP is not subject to the thrust due to vacuum, resulting in smooth, free-moving operation.
