BEARING PROTECTOR ABSTRACT OF THE DISCLOSURE A sealing device employing interfitting relatively rotatable rings, namely a stator and a rotor disposed for cooperation between a housing and a rotatable shaft. The stator is nonrotatably and sealingly engaged within an opening formed in the housing. An elastomeric O-ring maintains a seal between the stator and housing. he rotor snugly surrounds and is nonrotatably carried with the shaft and is provided with elastomeric seal ring therebet- ween to prevent leakage along the shaft. The stator closely externally surrounds the rotor to define a complex pathway therebetween which inhibits flow of liquids or contaminants in either direction therethrough. This pathway includes a pair of annular collecting chambers disposed in axially spaced relationship, whereby the outer chamber collects and discharges to the environment any contaminants which enter from the environment, and the inner chamber collects and discharges back to the reservoir any lubricant or fluid which enters into the pathway from its inner end.
