LINEAR ACTUATORS This Duff-Norton product line of actuators features load capacities ranging from 27 pounds to 25 Tons, gear or belt driven, acme screw and ball screw systems with various AC and DC input voltages. Duff-Norton Linear Actuators are specially designed for a variety of commercial and industrial applications. These actuators are used for opening and closing, tilting and pivoting, lifting and lowering and positioning. Applications include gates, dampers, oven and processing tank doors, antennas, orthopedic tables and other medical equipment, ergonomic furniture, and agricultural equipment, etc. Custom designs are also available for special applications. Linear Actuators are now being used in place of pneumatics and hydraulics when high maintenance and environmental problems (leaking hydraulic oil) are a concern.
