Abstract: Roller cone drill bits and methods of increasing the wear resistance of a roller cone drill bit are disclosed. The roller cone drill bit includes a plurality of rolling elements within a bearing assembly of a cone. Each rolling element of the plurality of rolling elements may have a surface hardness of HRC 59-63, a hardened depth that is 0.5 mm to 3.0 mm deep, and may be derived from a low carbon bearing steel material. The hardened depth is measured from the surface of each rolling element and the low carbon bearing steel material has, by weight percent, from 0.12% to 0.25% carbon.

Abstract: A track shoe includes a base plate, a grouser extending from the base plate, and at least one white iron member. At least a portion of the grouser includes a substantially martensitic structure. The at least one white iron member is fixed to a portion of the grouser.

Abstract: A bushing for a track assembly, according to one or more embodiments, includes: a tubular bushing substrate having a longitudinal length and an outer surface; and at least one white iron member fixed to the outer surface of the tubular bushing substrate.

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.
