NEMA Size 8 (20mm)
Hybrid Stepper Motor Linear Actuators

The NEMA 8 is our smallest hybrid linear actuator. This compact unit can be integrated into various applications to provide precise linear positioning while occupying less than 1 in 2 of mounting footprint and providing up to 10 lbsF (44.5N) of continuous thrust. Ball screw versions are also available.
