## Namura NA-30000R Piston Rings 65.96mm - Reliability and Performance Often overlooked, piston rings are a crucial element influencing engine performance, durability, and efficiency. The Namura NA-30000R piston rings with a diameter of 65.96mm guarantee the highest quality and precision. Designed for specific applications, they ensure optimal fit and long-lasting operation. ### Advanced Materials and Technologies Namura uses carefully selected materials in the production of NA-30000R piston rings, such as highly ductile cast iron or stainless steel alloy. This guarantees excellent wear resistance and sealing. Additionally, depending on the model, the rings can be coated with chrome, phosphate, or nitride, further increasing their durability and corrosion resistance. ### Compression Rings Compression rings, made of cast iron or stainless steel, ensure the tightness of the combustion chamber, minimizing pressure loss and optimizing engine performance. Chrome, phosphate, or nitride coatings further enhance their wear resistance. ### Oil Control Rings Oil control rings, consisting of two scraper rails made of highly ductile cast iron or stainless steel and a single expander ring made of stainless steel, effectively regulate the amount of oil on the cylinder walls, preventing it from entering the combustion chamber. This translates to lower oil consumption and cleaner combustion. ### Namura Brand - Synonym of Quality Namura is a renowned manufacturer of motorcycle and scooter parts, known for the high quality of its products. The NA-30000R piston rings are further proof of their attention to detail and commitment to providing solutions that meet the expectations of the most demanding users.
