Feature:1. Linear Actuator: Electric linear actuator is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion. It can be used to realize remote control, centralized control and automatic control.2. Work Principles: After the motor is decelerated by the gear, it drives a pair of screw nuts to turn the rotary motion of the motor into a linear motion, and uses the CW and CCW of the motor to complete the linear actuator action.3. Extensive Using: Can be used on electric treatment table, electric sofa, electric booth lifting rod, industrial electric lifting system, and so on.4. Great Materials: Consisting of high quality zinc alloy and aluminium alloy materials, has a sturdy structure and very durable for long term using.5. Easy to Install: Designed to have a light weight and a compact size as well, the convenient installation can be quickly finished.Specification:Item Type: Electric Linear ActuatorModel: JS TGZ U11Material: Zinc alloy, aluminium alloy.
