Screw spindle linear module

compact

Product Overview
The 15 mm frame PM stepper linear actuator is the most compact unit in the PM series, designed for installations with very limited space. External and Kaptive versions are offered to suit different integration requirements. Custom screw-end machining and bespoke stroke lengths are available as options.
