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: An idler group is disclosed for a mobile machine having a tracked undercarriage with an endless track. The idler group may include a retainer disposed on an axle and within an opening in an idler. The retainer may be configured to achieve an interference fit with the idler sufficient to hold the retainer within the opening of the idler during operation of the mobile machine. In another embodiment, a retaining ring may be disposed within a channel formed in the idler and may contact the retainer. In yet another embodiment, a swaged connection may be formed between the idler and the axle.
