Description

The C3802072 0.50 mm Main Bearing Set is an OEM-grade, oversize (under-size crank) bearing set specifically engineered for diesel engines requiring crankshaft regrinding or journal machining. When a crankshaft is machined undersize by 0.50 mm , these bearings restore the correct oil clearance, lubrication balance, and crankshaft support needed for reliable operation. Constructed using high-strength tri-metal bearing alloys, the C3802072 (0.50 mm) bearing set resists fatigue, heat, scoring, and friction—ensuring long service life in high-load, high-temperature diesel environments. Installing these bearings helps eliminate low oil pressure, knocking sounds, bearing failure, and uneven crankshaft wear often caused by worn or improperly sized bearings. This oversize bearing set is the trusted choice for engine rebuild shops, machine shops, fleet maintenance teams, and diesel technicians rebuilding high-performance or heavy-duty engines. ✔ Key Features & Technical Advantages OEM-spec C3802072 0.50 mm oversize main bearing set Designed for crankshafts reground or machined undersize by 0.50 mm Provides accurate oil clearance and crankshaft stability Reduces friction, heat buildup, and bearing wear Premium tri-metal alloy offers exceptional durability Prevents low oil pressure, bearing knock, and crankshaft scoring Ideal for major rebuilds, overhaul jobs, and crankshaft machining repairs
