Linear Actuators U2

The U2 model medical linear actuator is a low-noise, heavy duty motion linear actuator used for hospital beds, dental chairs, and other health care beds. Due to the metal gear box, its max pushing force is up to 8000N, which meets medical equipment requirements.

The front and rear ends of the U2 model motion linear actuator is made of ADC12 aluminum material, which offers a better durability than the U1 linear actuator. The sealing elements are surrounded by rubber material to ensure the waterproof performance, and users can choose different brake and overload protection types in customization services. To ensure compatibility with the control box, the U2 medical linear actuator’s outlet is different than the U1.

This type of linear actuator is equipped with a power adapter and manual controller, and one control box is capable of simultaneous control of 2 or 3 actuators. To meet customer requirements, this linear actuator can also be equipped with a power box in the event of power outages.
