| High Light | JAC Truck Crankshaft Main Bearing Shell ，1002412FA-1 ，1002412FA-1 Crankshaft Main Bearing Shell | ||
1002412FA-1 Crankshaft Main Bearing is the sliding bearing shell installed between engine main journal and cylinder block of JAC HFC4DA1-1 diesel engine. It bears alternating combustion impact loads and maintains a stable lubricating oil film to avoid direct metal contact between crankshaft and engine block. This aftermarket replacement bearing set fixes abnormal engine knocking, low oil pressure and journal scuffing triggered by alloy layer peeling, fatigue pitting and excessive clearance of worn bearings. Reliable lubrication protection extends crankshaft service life and prevents serious engine damage for light trucks working on heavy-load delivery and long-running logistics tasks.
Product Advantages Steel back combined with high-performance bimetallic alloy layer delivers strong load capacity and good embedability. Uniform thickness control ensures consistent running clearance. Surface oil distribution structure helps retain lubricant under shock load. Every bearing set passes thickness inspection and surface defect screening before shipment, OEM size for direct replacement during engine overhaul.
