MDrive Linear Actuator

MLI3 NEMA 23 External Linear CANopen IP20

MDrive CANopen NEMA 23 (57 mm) external linear actuator with expanded I/O set.

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, delivering 50 lbs (27 kg) of force for applications not requiring backlash and wear compensation, and an anti-backlash nut, for high accuracy and low drag torque with 25 lbs (11 kg) of thrust.

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
