150mm Stroke Linear Actuator 3000N Motor Actuator for Electric Lifting System Camera Rack 12V Item Type: Electric Actuator Material: ABS, Aluminum Alloy Stroke: Approx. 150mm / 5.9in Maximum Thrust: 3000N Frequency: 10% Protection Grade: IP54 Noise Level: <55db Main Uses: Electric medical bed, electric sofa, electric booth lifting rod, industrial electric lifting system, camera rack, projector, etc.Working Principle: The motor drives a pair of screw nuts after gear reduction. Turn the rotating motion of the motor into linear motion, and use the forward and reverse rotation of the motor to complete the actuator action. For example, complex actions such as turning and shaking can be completed through various mechanisms such as levers, rocker or connecting rods. By changing the length of the lever arm, the stroke can be increased or increased.
