Contamination Resistant Bearings and Bushings

Contamination Resistance, Long Life, Internal Seal

Extending bearing life and reduce associated safety risks for land vehicles and aircraft operating in contaminant-rich environments.

Our novel strategy addresses liner wear which can be accelerated by liquid and solid contamination in spherical bearings on fixed wing and rotorcraft with oscillating loads. This contamination-resistant bearing reduces contamination of airframe bearings without significant additional friction or cost, increasing bearing life, and reducing scheduled maintenance. The modification will not impact bearing installation time, procedures or required equipment. This patent-pending solution is targeted to the V-22 Osprey and other military rotorcraft being fielded in contaminant-rich environments, but has applications in construction equipment and motor vehicles. It can be adapted to custom and standard spherical bearing sizes, and is being developed and tested with a major bearing manufacturer.
