Engine Crankshaft Main Bearing Set MS 1804A By Clevite Copper Lead Cast Bearings Deliver About Twenty Percent Higher Fatigue Strength Versus Sintered Metals And Feature Beefy Aluminum Journal Interaction For Long Lasting Performance

Main crankshaft bearing set MS 1804A with copper-lead alloy
✔️ Copper-lead cast bearings with 100% bored diameters for precision

Engine crankshaft main bearing set designed for use in automotive and industrial engines. This copper-lead bimetal bearing delivers about 20% higher fatigue strength than sintered metals and features a harder aluminum journal interaction for long-lasting performance, especially on nodular iron crankshafts. It uses 100% bored inside diameters to ensure uniform surface characteristics and precise fit, meeting or exceeding OE specifications.

✅ 100% bored inside diameters for optimum surface characteristics and consistent precision
✅ Cast copper-lead bimetal construction improves fatigue strength vs sintered metals
✅ Aluminum silicon journal interaction for durable wear resistance
✅ Lead-free aluminum silicon alloy with enhanced silicon content improves journal conditioning
✅ OE-spec compliant to ensure proper fit and performance
