Our super duty linear actuators can be used in place of pneumatics or hydraulics. The super duty linear actuators are driven by high torque brushed DC gear motors coupled to a ball-screw to create a low friction linear drive. The ball-screw provides efficient linear thrust that can handle loads in both the pushing and pulling orientation. The linear actuators can handle an incredible amount of static load and will hold position even when power is removed. The actuators are equipped with independently adjustable limit switches in the base that will cut power when tripped to prevent over-run. Each actuator has a built-in potentiometer which can be used for positioning feedback if your application requires. The aluminum and steel construction with full metal drive gears ensures tremendous durability and reliability. Extension shaft is 1.125” diameter. Mounting holes are 1/2” diameter and bolt up directly to our optional mounting bracket. Note: These systems are extremely powerful and caution must be used during operation.
