Arconic Fastening Systems' spherical bearings and rod ends are designed and produced to withstand high loads, high temperature environments, vibration and corrosion. These bearings and rod ends are used in all types of aircraft applications such as nose and main landing gears, engine mounts, flight control surfaces, and doors.
The Trunnion bearings are specifically designed for landing gear applications. These bearings provide high load-carrying capabilities, while allowing some leeway for misalignment. The bearings are made from Copper Beryllium (ball) and 17-4PH and 15-5 PH (race) for maximum durability against corrosive and demanding working environments. To combat downtime and maintenance costs, Trunnion bearings allow for easy removal and replacement of the spherical ball. The ball provides maximum lubrication of all critical internal surfaces. The bore size range is “0.500 to 10.000”.
Rod ends and links
The Rod ends and links are used in elevated temperature environments. They also play an integral part of primary and utility actuation, engine controls, and various other engine and airframe applications. Rod ends and links are manufactured with externally threaded rod ends that are rolled for higher strength. The high-quality materials used include Stellite®, Copper Beryllium, Inconel® 718 and A286 in the ball, while the race consists of 17-4 PH, 15-5 PH, Inconel® 718 and A286. The bore size range is “0.125 to 2.000”.
Split ball bearings
The Split ball bearings are primarily utilized in secondary flight control systems like leading edge slats, trailing edge flaps and flight control actuators. They are designed for applications with dynamic or static loads that reduce the relative motion between the ball and race. Their high-quality construction results in superior race to ball conformity and more resistance to contamination. The split ball is easy to replace and remove as well. The Split ball bearings are constructed from Stellite®, Copper Beryllium, Inconel® 718 and A286 in the ball and 17-4 PH, 15-5 PH, Inconel® 718 and A286 in the race. The bore size range is “0.500 to 10.000”.
