Hybrid Stepper Motor Linear Actuator
LM23 NEMA 23 3.0 A 1.8° Non-captive Linear Stepper Motor
NEMA 23 (57 mm) 3.0 A, 1.8° non-captive linear actuator stepper motor delivering a maximum thrust of up to 200 lbs (91 kg)
Force -speed performance
100% current with damper simulating load.
Non-captive shaft linear actuators limit is 200 lbs / 91 kg. External shaft linear actuators limits are determined by the selected nut.
NOTE: Above performance data for maximum force/load is based on a static load and will vary with a dynamic 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
