20 Inch 500MM Waterproof Linear Actuator IP67 / Low Noise Linear Actuator (Model 0041942) Choose Stroke Rod Material for Linear Actuator::Aluminum Alloy Stroke and Length (Model 0041506-4)This is an IP67 waterproof electric linear actuator with a stroke of 500mm and a maximum thrust of 3500N (350 kg 780 lbs). The linear actuator is equipped with a waterproof breather valve, which allows air to freely flow in and out of the cylinder. When the linear actuator is running, a pressure difference will be generated inside and outside the cylinder, and air will flow in and out of the cylinder through the breather valve to ensure that the
