A track roller frame is provided for an endless track. The track roller frame includes a shaft including a body portion and a flange. A first bearing assembly rotatably supports a first rim portion on the shaft and a second bearing assembly rotatably supports a second rim portion on the shaft. Each of the first bearing assembly and the second bearing assembly includes a first leg that extends in the axial direction and is disposed along the body portion of the shaft and a second leg that extends in the radial direction and is disposed along the flange. A respective inner surface of each of the first rim portion and the second rim portion that faces the bearing assembly includes a plurality of lubricant pockets for receiving lubricant. Each of the lubricant pockets is configured and arranged such that lubricant contained therein is in fluid communication with the bearing assembly.

A track joint assembly pivotally links together track links of a continuous track. To form the track joint assembly, the first track link may include a male lug projecting from an edge of the track link that can be received between first and second side lugs projecting from the second track link. A floating bushing may be disposed inside a lug bore of the male lug and is in lubricated contact with the male lug. To retain the lubricant, first and second seals are disposed at either side of the floating bushing. A pin is inserted through both the floating bushing and lug apertures disposed through the first and second side lugs respectively. The pin may be in dry contact with the floating bushing and is either in a clearance fit or transition fit so that it can rotated with respect to the floating bushing.

A cartridge assembly for a track chain includes a bushing and a track pin. The bushing has an outer surface and an inner surface, the inner surface defining a passage in the form of a cylindrical bore. The bushing forms a lubrication reservoir adjacent the inner surface and extending towards the outer surface of the bushing. The track pin is disposed within the cylindrical bore, and the bushing is rotatable with respect to the track pin. An outer surface of the track pin is in fluid communication with the lubrication reservoir. The outer surface of the bushing corresponds with an outer diameter of the cartridge assembly. The outer diameter of the cartridge assembly is less than a diameter of supporting bores such that the cartridge assembly is rotatable with respect to inside surfaces of the supporting bores.

An track chain may comprise a first chain portion and a second chain portion each having a plurality of track links, and a plurality of joints interconnecting opposing track links of the first chain portion and the second chain portion. Each of the joints may include a bushing received by the opposing track links and the bushing may define a bore. Each of the joints may further include a pin received through the bore of the bushing, and the pin may have an outer diameter with at least one crowned region.

Overheating of the rollers in a track on mobile equipment can result in failure of the track. Accordingly, embodiments are disclosed for a temperature monitoring device that can be installed within an oil fill hole of each roller. Each temperature monitoring device may monitor the oil temperature within a respective roller, and communicate that oil temperature or other temperature indication to a controller. The controller may alert a human operator or another system when the temperature of a roller exceeds a predefined threshold that is indicative of overheating.
