Senior Aerospace Bird Bellows

What Senior Aerospace Bird Bellows does

Senior Aerospace Bird Bellows (legal entity Senior Bird Bellows Ltd.) is a UK-based, precision-engineering manufacturer of metallic bellows and flexible joint assemblies, operating as a wholly-owned subsidiary of the publicly-listed Senior PLC group. Founded in 1975 and headquartered in London with manufacturing concentrated in a 60,000 sq ft purpose-built facility, the company designs, manufactures, and qualifies bespoke flexible joints and pressure duct systems for high-temperature and high-pressure fluid and gas handling applications.

The product portfolio spans six core families used on commercial and military aircraft: bleed air systems, anti-ice systems, fuel systems, gimbal joints, ball joints, and metal bellows & assemblies. Manufacturing is conducted in-house on CNC tube benders, CNC lathes and machine centres, with robotic spot welding and polishing supported by an in-house metallurgical laboratory and purpose-built testing facility replicating aircraft operating environments. Materials expertise covers stainless steels, nickel alloys, titanium and other specialty alloys, and the business holds the full aerospace certification stack (AS9100, ISO9001, ISO14001, NADCAP welding and NDT). The go-to-market is direct enterprise sales to tier-1 aerospace and defence OEMs, evidenced by named relationships with Airbus, Rolls-Royce, Embraer, BAE Systems, Emerson and Curtiss-Wright, with the company claiming a zero-defect, zero-in-service-failure track record on delivered product.
