LEAP

CFM International has selected Sweden-based SKF to provide mainshaft and gearbox bearings for the LEAP high-bypass turbofan engine.

The ceramic hybrid mainshaft bearings are said to contribute to a lighter, quieter and fuel efficient aircraft engine.

LEAP engine is claimed to offer up to 16% lower carbon emissions compared to its predecessor CFM56.

SKF specialty business president Patrick Tong said: "Being involved in one of the industry’s most prestigious engine development programs is an exciting opportunity for us.
