Z Chain Slides

Provides short strokes of Z travel with a wide range of bellows I.D.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.


The slide is provided through three lead screws which are synchronously driven by a drive chain. Manual operation is provided by a handwheel assembly operating through a wormdrive reduction system. Z chain slides are often integrated with an XY stage. The unit is intended primarily for vertical operation with the load supported on the Z axis. For alternative orientations please contact our technical department. The Z chain slide can be motorised with the stepper motor shift.
