To urgently treat foreign-damaged plain bearings, a technical investigation is conducted through material analyses and hardness measurements. The British standard of bearing materials, BS-1200, G1, is based on the operating conditions and lubrication. This study investigates the wear engineering of a plain bearing with a marine winch shaft. An analysis of the investigated technology was intended to secure the function and quality of alternative KS standard materials that are equivalent to foreign products. Based on a comprehensive analysis of damaged foreign plain bearings, navy shipyard direct manufacturing was completed using equivalent-class KS bearing materials.
