A sealing system for a gear reducer includes a compound sealing arrangement disposed in a bore of the reducer housing through which a rotating member extends. The sealing arrangement includes an outboard shielding seal and a inboard lip seal disposed adjacent to one another. The shielding seal includes an annular metallic shield and forms a labyrinth with the rotating member. An elastomeric sealing member is bonded to the shield. The inboard seal provides at least two additional points of contact for sealing the rotating member. The arrangement defined multiple barriers to liquid and solid contaminants and seals lubricant within the reducer housing. Similar arrangements may be provided about several rotating members, and about ends of members extending through the reducer housing, such as an output hub.
