Lead Screws
Adjust. Protect. Deploy. Mission-Ready Seating Solutions.
Seat actuation systems in military and aerospace applications are critical for ensuring pilot comfort, situational readiness, and emergency responsiveness. Whether in fighter jets, transport aircraft, or tactical ground vehicles, reliable seat movement contributes to safety, ergonomics, and operational efficiency.
Helix Linear Technologies offers rugged linear actuators and lead screw assemblies engineered for high-force, precision-controlled seat motion. Our components support automated adjustments for recline, height, and lumbar positioning while also integrating into systems designed for ejection or rapid deployment.
Built to meet stringent aerospace and defense standards, Helix motion systems operate reliably under vibration, shock, and extreme environmental conditions, keeping aircrews and operators mission-ready at all times.
Key Benefits:
From comfort to combat readiness, Helix actuators are built to support the seat systems that support the mission.
