## Namura NA-10008-6R Piston Rings for 93.46mm, 93.47mm Pistons Often overlooked, piston rings are a crucial component for piston performance, engine efficiency, and longevity. The Namura NA-10008-6R piston ring set is designed for pistons with diameters of 93.46mm and 93.47mm, guaranteeing excellent engine performance. Namura is known for its high-quality components, and these rings are no exception. ### Materials and Construction The materials used in the production of Namura NA-10008-6R piston rings are a key factor influencing their performance. Designed specifically for their application, they take into account the type of cylinder sleeve, its coating, engine size, and stroke type (2 or 4). All these factors contribute to the selection of the optimal material composition best suited for the operating environment. ### Compression Rings Namura NA-10008-6R compression rings are made of highly ductile cast iron or stainless steel alloy. Both materials offer excellent wear resistance and provide a gas-tight seal. Depending on the application, chrome, phosphate, and nitride coatings are also used to meet the demands of challenging operating conditions. ### Oil Control Rings Namura NA-10008-6R oil control rings consist of three separate components: two scraper rails made of highly ductile cast iron or stainless steel alloy, coated with chrome, nitride, or phosphate, and a single expander ring made of stainless steel. This design ensures efficient oil drainage and prevents oil from entering the combustion chamber. By choosing Namura NA-10008-6R piston rings, you invest in the reliability and longevity of your engine.
