## Piston Rings 41.46mm Namura NX-30050-2R - Reliability and Performance Often overlooked, piston rings play a crucial role in ensuring optimal engine performance, efficiency, and durability. Namura, a renowned manufacturer of motorcycle and scooter parts, offers the NX-30050-2R piston rings with a diameter of 41.46mm, designed for superior quality and reliability. ### Advanced Materials and Technologies The materials used in the production of Namura piston rings are critical to their performance. The type of cylinder sleeve, its coating, engine size, and stroke (2 or 4-stroke) all influence the selection of the optimal material composition for the specific operating environment. Namura NX-30050-2R rings are precisely manufactured from high-quality materials, guaranteeing excellent sealing and wear resistance. ### Compression Rings Namura compression rings are made of highly ductile cast iron or stainless steel alloy. Both materials offer excellent wear resistance and provide a tight seal. Depending on the application, the rings may also be coated with chrome, phosphate, or nitride for enhanced durability and corrosion resistance. ### Oil Rings Namura 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, minimizing oil consumption and preventing it from entering the combustion chamber. ### Namura Brand - Guarantee of Quality By choosing Namura NX-30050-2R piston rings, you are investing in quality and reliability.
