## Namura NA-80001-6R Piston Rings 92.458mm - Reliability and Performance Namura NA-80001-6R piston rings with a diameter of 92.458mm are a key element ensuring optimal engine operation, efficiency, and durability. Often overlooked, piston rings play a crucial role in ensuring the tightness of the combustion chamber and proper lubrication. Namura, known for its high-quality motorcycle and scooter parts, designs its rings for specific applications, taking into account the type of cylinder liner, its coating, engine size, and stroke type (2 or 4). ### Advanced Materials and Technologies The materials used in the production of Namura piston rings are one of the most important factors influencing their performance. Both compression and oil rings are made of durable alloys, providing excellent wear resistance and sealing. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings guarantee excellent sealing and wear resistance. Additional coatings, such as chrome, phosphate, and nitride, increase their durability and adapt them to specific operating conditions. ### 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 one expander ring made of stainless steel. This design ensures optimal lubrication and prevents oil from entering the combustion chamber. ### Namura Brand Quality By choosing Namura NA-80001-6R piston rings, you are investing in quality and reliability. Precision manufacturing, material selection, and advanced production technologies guarantee long life and optimal engine operation.
