Track joint assemblies

A track joint assembly, comprising:

• a first link having a first bore;
• a second link having a second bore;
• a bushing including:
• a first axial end portion press-fit into the first bore, the first axial end portion having a first outer diameter smaller than a bushing outer diameter;
• and
• a second axial end portion press-fit into the second bore, the second axial end portion having a second outer diameter smaller than the bushing outer diameter;
• and
• a thrust ring positioned at an axial end of the first axial end portion, and having an outer diameter that is between approximately 1.1 and approximately 2.0 times an outer diameter of the first axial end portion.

A track joint assembly, comprising:

• a link having a bore;
• a bushing including an axial end portion disposed in the bore, the axial end portion having a first outer diameter smaller than a second outer diameter of the bushing;
• a thrust ring positioned at an axial end of the axial end portion, and including:
• a generally cylindrical outer surface;
• and
• a generally cylindrical inner surface including at least one protrusion extending toward a central axis of the thrust ring;
• and
• a seal assembly positioned radially outward of the outer surface of the thrust ring, and contacting the link at a seal-link interface.
