## Namura NX-40010-1R Piston Rings 56.20mm - Reliability and Performance for Your Engine The Namura NX-40010-1R piston rings, with a diameter of 56.20mm, are a crucial element ensuring optimal performance, efficiency, and longevity of your motorcycle or scooter engine. Often overlooked, piston rings play a vital role in maintaining combustion chamber seal and proper lubrication. Namura, a brand renowned for high-quality parts, offers a product that meets the demands of even the most discerning users. ### Advanced Materials and Technologies Namura NX-40010-1R piston rings are crafted from top-quality materials, carefully selected for specific applications. The type of cylinder sleeve, sleeve coating, engine size, and piston stroke - all these factors have been considered in the design process to ensure a perfect fit and optimal performance. ### Compression Rings Namura NX-40010-1R compression rings are made of highly ductile cast iron or stainless steel alloy. Both materials exhibit excellent wear resistance and provide a tight combustion chamber seal. Depending on the model, the rings may also be coated with chrome, phosphate, or nitride, further enhancing their durability and resistance to extreme temperatures. ### Oil Control Rings Namura NX-40010-1R 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. This design ensures efficient removal of excess oil, preventing it from entering the combustion chamber and minimizing oil consumption. By choosing Namura NX-40010-1R piston rings, you are investing in the reliability and longevity of your engine.
