Crankshaft Main & Connecting Rod Bearings Customized Manufacturing
Precision Bearing Manufacturing & Laser Cladding Restoration to OEM Specifications
Main and connecting rod bearings are critical components in 4-stroke diesel engines, ensuring reliable operation under high mechanical and thermal loads in marine and industrial applications. At KIMI, we specialize in both the custom manufacturing and repair of crankshaft main and crankpin bearings, precisely tailored to match crankshaft machining requirements. When OEM parts are unavailable, obsolete, or subject to long lead times, our solutions provide a reliable and cost-effective alternative. Bearings are manufactured using high-grade materials fully interchangeable with OEM and are finished to exact crankshaft dimensions.
All components undergo full verification in our ESYD ISO/IEC 17025 certified laboratory, ensuring dimensional accuracy, material integrity, and long-term operational reliability.
