## Namura NA-10008-2R Piston Rings - Reliability and Performance for Your Engine Often overlooked, piston rings are a crucial element influencing engine performance, durability, and efficiency. Namura NA-10008-2R, designed for pistons with a diameter of 82.46mm and 82.47mm, guarantees the highest quality and precision. ### Advanced Materials and Technologies The materials used in the production of Namura piston rings are one of the most important factors guaranteeing their excellent parameters. Namura designs its rings for specific applications, taking into account the type of cylinder sleeve, its coating, engine size, and stroke type (2 or 4). This allows for the selection of the optimal material composition, perfectly matched to the operating conditions. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings are characterized by exceptional wear resistance and provide a tight seal. Additionally, depending on the model, chrome, phosphate, and nitride coatings are used to meet the demands of the specific application. ### Oil Rings Oil rings consist of three separate components: two scraper rings 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 ensures optimal lubrication and prevents excessive engine wear. By choosing Namura NA-10008-2R piston rings, you invest in the reliability and longevity of your engine.
