## Piston Rings 58.88mm Namura NA-50100-6R - Reliability and Performance The Namura NA-50100-6R piston rings with a diameter of 58.88mm are a key element ensuring optimal engine performance. Often overlooked, piston rings have a huge impact on efficiency, durability, and combustion effectiveness. Namura, known for high-quality motorcycle and scooter parts, delivers a product that will meet the requirements of even the most demanding users. ### Advanced Materials and Technologies Namura NA-50100-6R are designed for the specific requirements of a given application. The type of cylinder sleeve, its coating, engine size, and piston stroke (2 or 4 stroke) - all these factors influence the selection of the appropriate ring material composition. Both compression and oil rings are made of highly durable alloys, guaranteeing excellent wear resistance and sealing. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings provide excellent sealing and minimize pressure loss. Additionally, chrome, phosphate, and nitride coatings increase their resistance to wear and corrosion, extending engine life. ### Oil Rings The oil ring set consists of three components: two scraper rings, made of highly ductile cast iron or stainless steel, and one expander ring made of stainless steel. Chrome, nitride, or phosphate coatings on the scraper rings prevent excessive wear and ensure optimal cylinder lubrication. ### Choose Namura Quality By choosing Namura NA-50100-6R piston rings, you are investing in the reliability and longevity of your engine. Precision manufacturing, high-quality materials, and advanced technologies guarantee optimal performance and maximum efficiency.
