Cryogenic Fine Positioning Linear Actuator
The Cryogenic Fine Positioning Actuator product is designed to produce very small linear output steps using conventional actuator technology. Actuation is accomplished by using a small angle stepper motor coupled to a large gear reduction transmission. The linear excursion is accomplished with a fine preloaded leadscrew mechanism to eliminate backlash.
