A track chain assembly comprising: a first track link including a first body defining a top surface, a bottom surface, a first side surface and a second side surface defining a thickness therebetween, a proximate end and a distal end, and a length therebetween; the first body defines a first bore with a first diameter disposed adjacent the proximate end and a second bore with a second diameter disposed adjacent the distal end, the first diameter being larger than the second diameter; a second track link including a second body defining a top surface, a bottom surface, a first side surface and a second side surface defining a thickness (T') therebetween, a proximate end and a distal end, and a length (L') therebetween; the second body defines a third bore with a third diameter disposed adjacent the proximate end and a fourth bore with a fourth diameter disposed adjacent the distal end, the third diameter being larger than the fourth diameter; wherein the third bore is aligned with the second bore, defining a common track link bore longitudinal axis; and characterized by a bearing assembly disposed in the third bore, the bearing assembly including a cylindrical configuration with a radial direction, a circumferential direction, and defining a bearing assembly longitudinal axis coaxial with the common track link bore longitudinal axis, a first axial end, and a second axial end; an inner radial race; an outer radial race; a bearing member disposed radially between the inner radial race and the outer radial race; and a retaining ring engaging the inner radial race and engaging the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race. a first track link including a first body defining a top surface, a bottom surface, a first side surface and a second side surface defining a thickness therebetween, a proximate end and a distal end, and a length therebetween; the first body defines a first bore with a first diameter disposed adjacent the proximate end and a second bore with a second diameter disposed adjacent the distal end, the first diameter being larger than the second diameter; a second track link including a second body defining a top surface, a bottom surface, a first side surface and a second side surface defining a thickness (T') therebetween, a proximate end and a distal end, and a length (L') therebetween; the second body defines a third bore with a third diameter disposed adjacent the proximate end and a fourth bore with a fourth diameter disposed adjacent the distal end, the third diameter being larger than the fourth diameter; wherein the third bore is aligned with the second bore, defining a common track link bore longitudinal axis; and characterized by a bearing assembly disposed in the third bore, the bearing assembly including a cylindrical configuration with a radial direction, a circumferential direction, and defining a bearing assembly longitudinal axis coaxial with the common track link bore longitudinal axis, a first axial end, and a second axial end; an inner radial race; an outer radial race; a bearing member disposed radially between the inner radial race and the outer radial race; and a retaining ring engaging the inner radial race and engaging the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race.
