Description
The Duff Norton LS26-1B5TN-04 Electric Linear Actuator is an electromechanical component designed to produce precise linear motion for positioning dampers, valves and other movable assemblies. The 4″ stroke defines the maximum travel distance, while the 560 lb load capacity allows it to push or pull heavy mechanical loads with controlled force. Operating on a 115V power supply, it converts rotary motor movement into straight-line motion through an internal drive mechanism. In HVAC systems, it is housed on automated control equipment to provide accurate positioning, dependable movement, and consistent operation during heating, cooling, and ventilation cycles.
