Bellows sealed linear actuators
The bellows sealed Linear Shift Mechanisms (LSMs) provide linear motion along the port axis (Z) with up to 1,000mm stroke and a range of clear bore options. Bakeable to 250°C, the range is supplied on CF flanges and provides true UHV performance.
The bellows are manufactured from 316L stainless steel as standard and offer a minimum design life of 10,000 cycles. Customised units are available offering a design life of up to 3 million cycles.

Magnetically-coupled linear actuators
For high-duty process applications, the magnetically-coupled push pull (MPP) devices are ideally suited with high torque, high axial stiffness and zero thrust due to vacuum. The magnetically-coupled push pull range provides linear and linear/rotary motion solutions with up to 300mm (12") stroke.
Strong magnetic coupling eliminates the use of bellows and dynamic seals, which are vulnerable to failure, providing a robust long-life design.
