Product Description
1002016FB040PK Crankshaft Main Bearing is the sliding bearing shell set fitted between crankshaft main journal and cylinder block of JAC HFC4DB2-1D diesel engine. It undertakes alternating impact loads from combustion and maintains continuous lubricating oil film, isolating direct metal contact between crankshaft and engine block. This aftermarket replacement bearing set fixes abnormal knocking noise from engine lower part, low oil pressure and journal scuffing caused by alloy layer flaking, fatigue pitting and over-limit clearance of aged bearings. Stable lubrication protection extends crankshaft service life and prevents catastrophic engine failure for light-duty trucks operating frequent start-stop urban delivery and heavy-load freight routes.
Product Advantages Steel back with high-performance bimetallic alloy layer provides outstanding load capacity and good conformability. Precision thickness control keeps uniform running clearance. Optimized surface oil distribution structure preserves oil film under shock loads. Each bearing set goes through thickness tolerance inspection and surface defect screening before delivery, OEM size for direct replacement during engine overhaul.
