Product Introduction

RIKMI main and connecting rod bearings for excavator engines are precision components developed for heavy-load, high-speed and continuous heavy-duty operations. They support the crankshaft and bear core engine pressure. Made of multi-layer tin-aluminum alloy via high-pressure sintering, our bearings feature high load capacity, fatigue and impact resistance, preventing common failures such as scoring, seizure, delamination and abnormal noise. The bearing surface adopts high-precision mirror polishing with standard oil grooves, which builds stable lubricating oil film to reduce friction and avoid dry burning. Curvature, clearance and thickness follow OEM standards for perfect fit without extra grinding. The special surface coating offers great heat and oxidation resistance to prevent peeling. With full model range for mainstream excavator engines, every bearing set passes pressure, fitting and durability tests. Reliable, low-failure and cost-effective, they are excellent choices for engine overhaul and bulk procurement.
