Abstract: A track roller for a mobile machine is disclosed. The track roller may have a shaft defining a central axis, and a roller body connected to the shaft and configured to rotate around the central axis relative to the shaft. The track roller may also have a sealing member positioned between the shaft and the roller body, and a collar member secured to the shaft and at least partially covering the sealing member. A passageway having an opening may be defined between the collar member and the roller body. The track roller may further have a guard member secured to the shaft, the guard member having a main body and an upper rim extending from the main body towards the roller body. The guard member may also have a plurality of projections extending from the main body towards the roller body, and a plurality of openings formed between the upper rim and the projections.

Abstract: A face seal member includes a cylindrical annular body defining a cylindrical axis, a radial direction, a first axial extremity, a second axial extremity, an outside radial extremity and an inside radial extremity, a face sealing surface including a clearance surface, a contact region disposed radially adjacent the clearance surface that defines a contact plane, and a tapered surface extending radially from the contact region that defines a taper angle with the contact plane that increases as the tapered surface progresses further radially from the contact region toward the inside radial extremity.
