## Namura NX-20006R Piston Rings - Reliability and Performance for Your Engine Namura NX-20006R piston rings, designed for pistons with diameters of 53.96mm, 53.97mm, and 53.98mm, are a key component ensuring optimal performance, efficiency, and longevity of your engine. Often overlooked, piston rings play a vital role in maintaining proper compression and lubrication. Namura, renowned for its high-quality motorcycle and scooter parts, offers a product that will meet the expectations of even the most demanding users. ### Advanced Materials and Technologies Namura utilizes carefully selected materials and advanced technologies to ensure maximum durability and performance of its piston rings. The type of cylinder sleeve, its coating, engine size, and stroke (2 or 4 stroke) – all these factors influence the selection of the appropriate ring composition. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings are characterized by excellent wear resistance and provide a tight seal. Additionally, chrome, phosphate, and nitride coatings enhance their durability and corrosion resistance. ### Oil Rings Oil 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 removal of excess oil and prevents it from entering the combustion chamber. By choosing Namura NX-20006R piston rings, you invest in the reliability and longevity of your engine.
