Product Introduction

RIKMI cylinder liners for excavator diesel engines are premium core components designed for heavy-load, high-wear, high-temperature and high-pressure working conditions. Made of high-hardness alloy cast iron with special smelting purification, they feature uniform and dense metallographic structure, outstanding hardness, toughness and crack resistance. They effectively avoid common failures like scratching, grooving, out-of-round deformation and premature wear, suitable for long-hour operation in mining and earthmoving projects. Manufactured via precision CNC boring and mirror honing, the inner wall has uniform texture for good oil storage, reducing friction and preventing cylinder scuffing and oil burning. Dimensions comply with OEM standards with precise roundness and verticality for easy fitting. Each liner passes hydraulic pressure, compression and wear tests. It maintains stable shape under high temperature to guarantee reliable sealing, boost power and cut fuel consumption. With full model coverage for mainstream excavators, RIKMI liners are high-quality, cost-effective overhaul parts with low failure rates.
