Linear Actuators - Stepper

57DBM-L Permanent Magnet Stepper Digital Linear Actuator

Permanent Magnet Stepper Digital Linear Actuator

The largest of linear actuator line, the 57DBM-L is a non-captive linear actuator that provides a long stroke length and up to 448 oz of linear force in a 57 mm frame size making it well suited for high force applications. Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including gearboxes and wiring / connector options please contact our sales and applications support team.

Motor Highlights
