More Information
Summary:A railroad coupler assembly (200) having at least a body (204) and a knuckle (208) both formed in a no-bake manufacturing process, the body and the knuckle having dimensional tolerances of distances between features that wear during operation that are about half those obtained from a body and a knuckle manufactured by a green sand process, resulting in increased fatigue life compared to the body and the knuckle manufactured by a green sand process.
