Product Highlights
- Control effect: linear actuators can be used as execution machinery in various simple or complex processes to achieve long distance control, centralized control or automatic control.
- Rugged: linear actuator is robust and can withstand harsh working environments. can also be used in smart home applications, thus providing smooth integration with all systems.
- Working principle: the electric linear actuator is an electric drive device that transforms the rotational motion of the electric motor into the linear reciprocating motion of the actuator. the electric motor is decelerated by gears and drives a pair of screw nuts. by changing the length of the lever force arm, the stroke can be increased or enlarged.
- Main applications: the linear actuator is suitable for electric beds, electric sofas, electric booth lift bars, industrial electric lift systems, camera stands, and wedding systems.
- Easy to install: linear actuator is easy to install and easy to integrate for woodworking and home improvement. the electric linear actuator turns the rotation motion of the motor into a linear motion, using the motor forward and reverse to complete the actuator action.
