A Linear Actuator converts the rotational motion of an AC or DC motor (torque) into a straight line motion, providing push and pull movements. Actuators can be used to tilt, pivot, lift, lower, position, roll, slide, open, close, or tension a piece of equipment, product, or device, via a solid shaft extension system. This action can be fast, precise and controlled with OEM equipment.

Within each unit are gears, lead/ball screw, and a driving nut that changes the position of the shaft. As power is applied, the nut runs up and down the screw, converting the rotary motion into linear motion.


How Can a Linear Actuator Move?

Tilt/Pivot: can be used to tilt objects, fixed at one end, up to 180-degrees from their starting position. The extension and retraction of the actuator causes the object to pivot about its stationary end.

Lift/Lower: can handle any lifting and lowering application. As the translating tube of the actuator extends and retracts, the object that the actuator is attached to is raised and lowered at a consistent speed.

Position: When an application required periodic adjustment to the position of an object(s), the motion of the actuator allows the operator to position an abject by simply pushing a button.

Roll/Slide: When it is necessary to roll of slide an object or a mechanical assembly into position the movement of the actuator causes the clamping, rolling, or sliding of the desired object.

Open/Close: Mounted on a door, gate, or valve allows the opening and closing operations on either a timed or non-demand basis. As the actuator retracts, the gate is opened at a steady rate; the extension of the actuator returns the gate the a closed position.

Tension: Offering a perfect solution for applications in which tension on a conveyor or web must be maintained and adjusted. An actuator mounted on a frame or roller extends and retracts to control the tension in the system.
