Well known bearing companies Dupont an American company and Fujian Longxi Bearing (Group) Corporation Limited (LS) from China have joined forces to be able to create a new innovative bearing to bring to the industry. Them both have created a self-lubricating bearing that is meant to be able to enhance capability and be able lower the amount of maintance cost for corporations due to its self-lubrication properties.
This new innovative bearing has been designed to be incorporated in the airframe control systems. These bearings parts will be a huge contribution to aircraft applications that pertain to certain aircraft functions. This bearing will be a crucial part for landing gear in the aircraft.One of the big reasons for having Fujian Longxi on board with the bearing project was due to it being the only Navair certified company in China.
“The DuPont™ Vespel® bearing liner 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 if the industry average. This means longer maintenance intervals, meaning lower cost in operation, less maintenance time, and more time in the air!”
Many company and owners are caught the low cost in maintance intervals when they are aware of the innovative bearing which reduces intervals. The average interval that the standard bearing can under go before having to need maintance is at an approximate 25,000 cycles. With the new innovative self-lubricating bearing the average intervals it is able to reach a 100,000 before it requires maintance, almost three times as much!DuPont™ Vespel® CP materials has ventured out from its usual production of aircraft engines to be able to join in with the production of the bearing.
“DuPont Performance Materials (DPM) is a leading innovator of thermoplastics, elastomers, renewably-sourced polymers, high-performance parts and shapes, as well as resins that act as adhesives, sealants, and modifiers.”
Fujian Longxi Bearing Is the essential bearing part to this partnership. “Fujian Longxi Bearing (“LS”) specializes in the production of spherical plain bearings (SPB), tapered roller bearings, gears, gearboxes, and automobile parts.”
