Cylinder liner type, liner coating, engine size, and piston stroke (2 or 4) – all these factors influence the selection of the optimal material composition to meet the demands of the operating environment. ### Compression Rings Made of highly ductile cast iron or stainless steel alloy, the compression rings are characterized by excellent wear resistance and provide a tight seal. Chrome, phosphate, and nitride coatings further enhance their durability and corrosion resistance. ### Oil Rings 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 expander ring made of stainless steel. The oil rings' function is to precisely meter the oil, minimizing its consumption and preventing excessive burning. ### Why Namura?
