Product Introduction

RIKMI piston rings for excavator engines are specially developed for heavy-duty working conditions with high temperature and frequent reciprocating friction. As critical parts for sealing, oil control and pressure stabilization, they are made of high-strength alloy steel with carburizing and nitriding hardening treatment. Featuring high surface hardness and great toughness, they resist wear, fatigue and breakage, avoiding common defects such as tension loss and ring sticking. Designed with precise end gap, face profile and tension matching OEM specifications, they fit perfectly. Compression rings seal combustion gas to maintain power output, while oil rings scrape oil evenly to stop oil burning, blue smoke and carbon buildup. With special anti-wear and anti-corrosion coating, they withstand high temperature and oxidation. Full models fit Komatsu, Caterpillar, Hitachi, Doosan, Sany . Each set passes tension, sealing and durability tests. Reliable and cost-effective with low return rate, they are ideal for engine overhaul and bulk orders.
