Among the largest of Duff Norton’s DC-powered linear actuators, MPD Series models offer a 500 lbs. capacity for lifting, lowering, and motion control, with a 750 lbs. static load limit. Acme screw designs with adjustable internal limit switches or clutches (varies by model) provide superior performance. 12 or 24 VDC motors provide speeds up to 0.85 in/sec (22 mm/sec). Stroke lengths of 3”, 6”, 12” or 18” (76 mm, 152 mm, 304 mm, or 457 mm) are available.

Linear Actuator Selection Guide
To determine which DC-powered linear actuator is best for your application, consider the factors below. As needed, C.H. Bull is available to help you select the right model for your unique needs. Contact us to discuss your application requirements.
- Capacity: The force required the move and hold the load (total weight of the load)
- Voltage: The voltage needed to power the actuator
- Travel: The distance/range of motion required (stroke)
- Speed: The speed at which the load must be moved
- Duty Cycle: Percentage of time an actuator is in motion relative to total time
- Orientation: The direction in which the actuator’s force is applied
- Environment: The working conditions in which the actuator will operate
