Schaeffler Group’s member FAG Aerospace has developed a new aircraft engine ball bearing that is claimed to make engines more efficient.
The bearing uses minimal cooling oil quantities, and is said to exceed the speed parameter of four million millimetres per minute.
It features integrated oil damping of vibration loads and performance-enhanced, duplex-hardened raceways that offer strength and wear-resistance, while reducing the rolling contact loads.
The technology is claimed to help lower the global passenger aircraft fleet’s fuel by 200,000t year.
The ball bearing has been developed as part of the ‘Effective Oil System’ collaborative project under the Aviation Research Program (LuFo), which is supported by the Federal Ministry for Economic Affairs and Energy.
