151PL18396000 MAHLE Connecting Rod Bearing

Engine Bearings from MAHLE (MPN: 151PL18396000) are designed to support the crankshaft in your engine, ensuring smooth operation and reducing wear on moving parts. Typically used in passenger vehicles and commercial fleets, these bearings contribute to improved fuel economy and extended engine life by minimizing friction. Crankshaft bearings are precision components facilitating smooth rotary motion between the crankshaft and engine block. Located within the engine’s main and connecting rod bearing bores, these bearings support significant loads and reduce friction generated by reciprocating piston motion. Typically manufactured from tri-metal or polymer-coated steel, they feature a split design for ease of installation and precise clearance control. Oil grooves and channels within the bearing surface maintain a hydrodynamic oil wedge, preventing metal-to-metal contact. Dimensional accuracy and material hardness are critical for maintaining engine performance and longevity, with variations existing for different engine families and load requirements.
