DuPont and Fujian Longxi – the next step in Aircraft control

June 15, 2017

With the help of Allawos & Company, DuPont and Fujian Longxi Bearing (Group) Corporation Limited (“LS”) have teamed up for the 2017 Paris Air Show to present their collaboration on the design and manufacture of innovative spherical bearings in aircraft design.

DuPont and Fujian Longxi, the only Navair (AS81820 Type A, MS standards) certified company in China, have worked together to develop self-lubricating bearings for use in the actuation of airframe control systems. The collaboration, which began in 2016, brings spherical bearing design and wear resistant liner expertise together into a superior performing bearing family which play a vital role in critical tasks such as flight control systems, landing gear, and a wide range of other aircraft functions. These bearings, which improve performance and reduce cost for aerospace companies are on the market now DuPont and Longxi will offer solutions for a wide range of aviation applications, such as mechanical and fly-by-wire flight control systems, helicopter rotor controls systems, landing gear, doors, engine controls, thrust reversers, VGV systems, blocker doors and airframes.

The DuPont™ Vespel® bearing liner for self-lubricating bearings has been successfully applied to the Fujian Longxi spherical bearing, allowing the bearings to meet the stringent new standards of SAE AS81820 type “A” attaining maintenance free certification for 4 times as long as the industry average.

DuPont will work with Aircraft Engine and Nacelle OEMs to offer the best liner solutions, while Fujian Longxi will develop bearing solutions applications for Fixed Wing Aircraft, and helicopters.

Mr. Loic Chereau, global aerospace segment leader for Vespel® at DuPont Performance Materials (DPM), stated that “We are delighted to present the fruits of our collaboration at the Paris Air Show. There is no better place to show how these bearings create new and exciting opportunities in for our customers”.

Longxi’s Chairman of the Board Mr. Zeng stated that “global cooperation such as this is key in achieving technological breakthroughs and we very much look forward to presenting our solutions at the Paris Air Show”
