Taking the concept of solid lubrication to an even higher-level Gotoh have developed a new process of application for their exclusive “510 and “X” series gears. By creating a “Complex lubricating plating layer”, surface of all the moving gears have been coated through an Electro Plating process and are now enhanced with GSP that is a GOTOH original polymer compound specifically formulated to work with Gotohs LUBRI-COAT. With a “Solid Lubrication Coat”, oil has been eliminated keeping the lubrication where it is needed for the life of the tuning machine heads.
