## Piston Rings 58.74mm Namura NA-30160-2R - Reliability and Performance for Your Engine The Namura NA-30160-2R piston rings with a diameter of 58.74mm are a key component for ensuring optimal performance, durability, and efficiency of your motorcycle or scooter engine. Often overlooked, piston rings play a fundamental role in ensuring the tightness of the combustion chamber and proper cylinder lubrication. The Namura brand is a guarantee of quality and precise manufacturing. The NA-30160-2R rings are designed for the specific requirements of their application, taking into account the type of cylinder sleeve, its coating, engine displacement, and stroke type (2 or 4). ### Advanced Materials and Technologies Namura uses advanced materials and technologies to ensure maximum durability and wear resistance. #### Compression Rings: Made of highly ductile cast iron or stainless steel alloy, the compression rings guarantee excellent sealing and minimize compression losses. Additional chrome, phosphate, or nitride coatings increase their resistance to abrasion and corrosion. #### Oil Rings: The oil ring set consists of two scraper rails made of highly ductile cast iron or stainless steel alloy, also coated with chrome, nitride, or phosphate, and one stainless steel expander ring. This ensures effective scraping of excess oil, preventing it from entering the combustion chamber and maintaining optimal cylinder lubrication. ### Benefits of Choosing Namura NA-30160-2R Rings: * **Increased engine performance:** Thanks to the precise fit and high tightness, Namura rings improve compression and minimize power losses. * **Extended engine life:** Durable materials and advanced manufacturing technologies ensure a long service life of the rings and protect the cylinder from wear. * **Optimal lubrication:** Effective oil scraping prevents oil burning and ensures proper cylinder lubrication. * **Namura brand quality:** By choosing Namura rings, you are investing in proven quality and reliability.
