## Piston Rings 83.44mm Namura NA-50002-2R - An Essential Element for Efficient Engine Performance Piston rings, often overlooked, are a key component influencing engine performance, efficiency, and durability. Namura, a renowned manufacturer of motorcycle and scooter parts, offers piston rings NA-50002-2R with a diameter of 83.44mm, designed to ensure optimal performance. ### Why choose Namura piston rings? The Namura brand focuses on quality and precision. NA-50002-2R piston rings are made of high-quality materials, carefully selected for specific applications. The type of cylinder sleeve, sleeve coating, engine size, and piston stroke (2 or 4 stroke) - all these factors influence the selection of the optimal ring composition. ### Advanced technology for maximum performance * **Compression Rings:** Made of highly ductile cast iron or stainless steel alloy, they provide excellent wear resistance and a tight seal. Additional chrome, phosphate, or nitride coatings enhance their durability and resistance to extreme temperatures. * **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 expansion ring made of stainless steel. Their task is to efficiently remove excess oil, preventing it from entering the combustion chamber. ### Technical parameters: * Piston diameter: 83.44mm By choosing Namura NA-50002-2R piston rings, you invest in the reliability and longevity of your engine.
