Duff Norton linear actuators range in capacities from 27 pounds to 25 Tons!  Duff-Norton MPD Series Linear Actuators are specially designed for a variety of commercial and industrial applications: opening and closing, tilting and pivoting, lifting and lowering and positioning.  Possible applications include gates, dampers, oven and processing tank doors, antennas, orthopedic tables and other medical equipment, ergonomic furniture, and agricultural equipment.  In addition, linear Actuators are used instead of pneumatics and hydraulics when high maintenance and environmental problems (leaking hydraulic oil) are a concern.  With options such as gear or belt driven, acme screw, and ball screw systems, we can find your custom MPD Series actuator solution!  Request A Quote!
