## Namura NA-50098R Piston Rings 92.95mm - Reliability and Performance for Your Engine Namura NA-50098R piston rings with a diameter of 92.95mm are a key component for ensuring optimal performance, efficiency, and longevity of your engine. Often overlooked, piston rings play a vital role in sealing the combustion chamber and controlling oil consumption. Namura, known for its high-quality motorcycle and scooter parts, offers piston rings designed for specific applications, guaranteeing a perfect fit and reliability. ### Advanced Materials and Technologies Namura uses carefully selected materials and advanced technologies to ensure maximum performance and durability of its piston rings. The type of cylinder liner, its coating, engine size, and piston stroke (2 or 4 stroke) - all these factors influence the selection of the optimal material composition for a given operating environment. ### Compression Rings Compression rings, made of highly ductile cast iron or stainless steel alloy, are characterized by excellent wear resistance and provide a tight seal of the combustion chamber. Additional chrome, phosphate, and nitride coatings increase their durability and corrosion resistance. ### 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 one expander ring made of stainless steel. This design ensures efficient scraping of excess oil and maintains optimal cylinder lubrication. ### Namura Brand - Guarantee of Quality By choosing Namura NA-50098R piston rings, you are investing in proven quality and reliability.
