Description

The Cummins Fractured-Cap Connecting Rod Bearing C4893693 (Standard Size) is a precision-engineered bearing shell specifically designed for fractured-cap connecting rods , where exact alignment and bearing crush are critical. Manufactured to OEM specifications, this bearing ensures accurate oil clearance, stable crankshaft journal support, and long-term durability in Cummins diesel engines . Fractured-cap connecting rods use a fracture-split mating surface that requires bearings built to extremely tight tolerances. The C4893693 rod bearing is engineered to match these unique rod geometries, helping maintain correct journal alignment, consistent oil film thickness, and smooth engine operation under high combustion loads. Produced using high-quality bearing alloys with advanced overlay technology, this fractured-cap rod bearing offers excellent load-carrying capacity, fatigue resistance, and protection against metal-to-metal contact. Precision shell geometry promotes even load distribution, reduced friction, and extended crankshaft life in heavy-duty and emissions-controlled diesel applications. The Cummins C4893693 fractured-cap rod bearing is commonly installed during engine rebuilds, bottom-end overhauls, and professional remanufacturing projects . For engines with reground crankshafts, multiple undersize options are available to restore proper oil clearance and ensure reliable performance.
