## Namura NA-50002-6R Piston Rings 84.44mm - Reliability and Performance for Your Engine Namura 84.44mm NA-50002-6R piston rings are a key component in ensuring optimal engine performance, efficiency, and longevity. Often overlooked, piston rings play a fundamental role in the proper functioning of any combustion engine. Namura, a renowned manufacturer of motorcycle and scooter parts, delivers top-quality piston rings designed for the specific requirements of each application. ### Advanced Material Technology The selection of appropriate materials for piston ring manufacturing is crucial for their effectiveness. Namura utilizes highly durable cast iron and stainless steel alloys, characterized by excellent wear resistance and providing a tight seal. Additionally, depending on the model, the rings can be coated with chrome, phosphate, or nitride coatings to meet specific engine operating requirements. The type of cylinder sleeve, its coating, engine size, and stroke type (2 or 4) – all these factors influence the selection of the optimal material composition. ### Compression Rings Compression rings, made of highly ductile cast iron or stainless steel alloy, ensure a tight seal in the combustion chamber. Chrome, phosphate, or nitride coatings further enhance their resistance to wear and corrosion, contributing to a long engine life. ### Oil Control Rings 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. Their task is to effectively remove excess oil, preventing it from entering the combustion chamber and minimizing oil consumption. By choosing Namura 84.44mm NA-50002-6R piston rings, you invest in the reliability and performance of your engine. Precise manufacturing, high-quality materials, and advanced technology guarantee optimal performance and long service life.
