Aircraft Seat Actuators

Aircraft seat actuators are the core components of aircraft seating adjustment systems, primarily used to control functions such as seatback recline, legrest extension, height adjustment, and position locking. They provide passengers with personalized comfort while ensuring flight safety.

Leveraging extensive experience in development and design, our company has produced over 200 part numbers of actuators that are widely utilized by major airlines worldwide. Typically composed of a cylinder, piston rod, transmission mechanism, and control interface, these actuators receive electrical signals or mechanical commands from the seat control panel to drive linear motion. This movement enables the seat structure to achieve precise adjustments.

Our products meet stringent aviation standards: they feature lightweight construction (utilizing aluminum or titanium alloys to reduce aircraft load), high reliability (withstanding tens of thousands of operational cycles without failure), and environmental resistance (operating within a temperature range of -55°C to 85°C and under high-altitude low pressure). Additionally, they are certified for fire resistance, corrosion protection, and impact resistance, complying with airworthiness regulations such as FAA, EASA, and CAAC standards.

Widely applied in civil aircraft (economy, business, and first-class seats), business jets, and helicopter seating, these actuators are key components enabling intelligent and ergonomic seat adjustments. They directly enhance passenger comfort during long-haul flights and contribute significantly to airline service quality.
