  5. Bakeable to 250°C 



The Magnetic Push Pull range provides linear and linear plus rotary motion solutions with up to 250mm (10”) stroke. This compact range is specifically designed for low load applications, such as specimen transfer, thermocouple ‘contacting’ or manual shutters, for high or ultra high vacuum applications.


Utilising UHV Design’s magnetic coupling technology removes the need for edge-welded bellows, incorporated within traditional ‘push pull’ designs. Their elimination maximises vacuum integrity, providing a robust, cost effective solution. Also, unlike a bellows-sealed device, the Magnetic Push/Pull is not subject to the thrust due to vacuum, resulting in smooth, free-moving operation.


The range consists of three series with varying actuation options such as manual, pneumatic and stepper or DC motorised.


The Magnetic Push Pull range provides a simple and intrinsically safe alternative to bellows push pull systems.
