001AS19793000 MAHLE Thrust Washer, crankshaft

MAHLE Engine Bearings (MPN: 001AS19793000) are designed for use in crankshafts within engines. These bearings provide several key advantages: they increase the engine's lifespan by reducing wear on moving parts, improve fuel economy through optimized energy transfer, and contribute to a quieter operation. 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.
