Besides increasing the surface hardness and wear resistance by using Hard Anodizing treatment, these Hiro Seiko pinion gears have been impregnated with Molybdenum disulfide (MoS2) for ultra low friction.
MoS2 is known as Molybdenum disulfide which is an inorganic compound composed of molybdenum and sulfur. Molybdenum disulfide (MoS2) is a solid material with lubricating properties. It is widely used in engine lubricants and grease for construction machinery.
