NEMA 17 (42 mm) 1.5 A, 1.8° external linear actuator stepper motor delivering a maximum thrust of up to 25 lbs (11 kg) with general purpose nut.
Our linear motors feature precision rolled lead screws which are designed specifically for motion control applications to deliver maximum life and quiet operation. Corrosion resistant and non-magnetic, screws are manufactured from premium grade stainless steel. Screws may optionally be ordered with Teflon coating.
Mechanical nut options include a general purpose nut, for applications not requiring backlash and wear compensation, and an anti-backlash nut, for high accuracy and low drag torque. Note that use of an anti-backlash nut greatly reduces the maximum force which may be applied to a load.

Leadscrew maintenance statement
While under optimal conditions lubrication interval is expected to occur approximately once every 1000 hours of service. Actual life will depend on application and environment. Based upon this, frequent inspections must be performed and a maintenance interval determined based on actual conditions.
Recommended lubricant: Dupont Krytox GPL 206
