MPPRL - rotary and linear motion

MPPRL series

Linear & rotary motion

Magnetically-coupled push pull devices providing rotary and linear motion solutions for low-load applications in both high and ultra-high vacuum. Provided on a CF16 flange as standard with a choice of stroke lengths from 50mm to 300mm.  The MPPRL provides linear and continuous rotary motion of the vacuum shaft.

The range provides a simple and intrinsically safe alternative to bellows-sealed push pull systems and is ideal for high-duty-cycle/performance-critical applications, such as synchrotrons and MBE systems, where downtime is not acceptable. Linear strokes between 50mm and 300mm are offered as standard, with special strokes available upon request.

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. Unlike a bellows-sealed device, the MPPRL offers the additional advantage of not being subject to thrust due to vacuum, resulting in smooth free-moving, user-friendly operation.
