Abstract
A bearing seal for the outer and inner blade angle bearings of a rotor hub of a rotary wing aircraft comprises a lubricating oil chamber interconnecting the inner and outer bearings and extending coaxially therebetween. The bearings are provided with sealing rings at their faces opposite the lubricating oil chamber. A shielding member is positioned in front of the face of the outer blade angle bearing facing the lubricating oil chamber. A receptacle is arranged as part of the chamber and positioned in operative relationship with the deflector member for entrapping particles contained in the lubricating oil and separated therefrom by the effect of centrifugal forces as the oil migrates from the inner blade angle bearing toward the outer bearing.
