The benefits of using Composite Bearings in Aircraft Shock Absorbers 2019-01-1898
This paper will use actual examples from aircraft recently introduced into service, to describe the main advantages of changing from the currently used metallic bearings, to composite bearings.
The introduction of composite bearing in a recently introduced twin aisle aircraft has resulted in:
• Weight saving, by replacing bronze bearings with plastic bearings
• Lowering of the particle count in the shock absorber oil, (Reduced contamination with metal particles) leading to reduced wear on seals and bearings.
Qualification testing showed that Composite Bearings are able to provide longer service life than bronze bearings.
