Linear actuator is a kind of equipment that replaces hydraulic and pneumatic system performs push-pull action by using controller as an electricity provider. Linear Actuator’s operation is linear, which requires the Linear Actuator body to remain horizontal during its installation. Linear Actuator has precise control over its operations, which guarantees safety, low noise and pollution. Compared to hydraulic system, the installation of Linear Actuator is very easy. Light weight, compact structure, user-friendliness and high rigidity are the features of it. No pump and hose mechanical components inside allows utility of the room.
