## Namura NA-20062-2R Piston Rings 76.45mm - Reliability and Performance Namura NA-20062-2R 76.45mm piston rings are a key element for optimal engine performance. Often overlooked, these rings play a fundamental role in ensuring efficiency, durability, and a tight seal. Namura, known for its high-quality motorcycle and scooter parts, designs piston rings with the specific requirements of each engine in mind. ### Material Selection and Technology Namura NA-20062-2R piston rings are manufactured using carefully selected materials such as highly ductile cast iron and stainless steel alloys. The cylinder sleeve type, its coating, engine size, and stroke type (2 or 4) all influence the selection of the appropriate ring composition, guaranteeing a perfect fit for the operating conditions. Additionally, chrome, phosphate, and nitride coatings enhance wear resistance and provide excellent sealing. ### Compression Rings The compression rings, made of highly ductile cast iron or stainless steel alloy, are characterized by excellent wear resistance and provide a tight seal for the combustion chamber. Applied coatings, such as chrome, phosphate, or nitride, further enhance their durability and effectiveness. ### Oil Control Rings Oil control rings consist of three components: two scraper rails made of highly ductile cast iron or stainless steel, coated with chrome, nitride, or phosphate, and a single expander ring made of stainless steel. This design ensures efficient removal of excess oil, preventing it from entering the combustion chamber and maintaining optimal lubrication. ### Namura Brand Quality By choosing Namura NA-20062-2R piston rings, you are investing in quality and reliability. The Namura brand is a guarantee of precision manufacturing and the use of advanced technologies, resulting in long life and trouble-free engine operation.
