Abstract
A bushing assembly for a track assembly includes a first end element, a second end element, and a central element positioned between the first end element and the second end element. The central element may be interference fit or positioned between the first end element and the second end element, and the central element may include a greater hardness than the first and second end elements. The first end element, the second end element, and the central element form a bushing with a longitudinal opening extending longitudinally through the bushing.
