## Namura Piston Rings 77.45mm NA-20062-6R - Reliability and Performance for Your Engine Namura 77.45mm NA-20062-6R piston rings are a key component for optimal performance, efficiency, and longevity of your motorcycle or scooter engine. Often overlooked, these rings play a vital role in ensuring combustion chamber sealing and proper lubrication. Namura, a renowned manufacturer of two-wheeler parts, utilizes the highest quality materials and advanced technologies to guarantee reliability and long product life. ### Advanced Materials and Technologies Namura tailors the composition and construction of piston rings to the specifics of individual engines. Factors such as cylinder liner type, liner coating, engine displacement, and stroke type (two- or four-stroke) are taken into account during design to ensure a perfect fit and optimal performance under all conditions. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings feature excellent wear resistance and provide a tight seal for the combustion chamber. Additional coatings like chrome, phosphate, and nitride enhance durability and prevent excessive wear. ### Oil Rings Oil rings consist of three components: two scraper rails made of highly ductile cast iron or stainless steel, coated with chrome, nitride, or phosphate, and a single expander ring made of stainless steel. This design ensures effective cylinder lubrication and minimizes oil consumption. ### Specifications: * Piston Diameter: 77.45mm By choosing Namura NA-20062-6R piston rings, you invest in quality, reliability, and the long life of your engine.
