099AS21073000 MAHLE Thrust Washer, crankshaft

MAHLE's Engine Bearings (MPN: 099AS21073000) are precision-made for optimal performance. They measure 145.0 x 29.0 x 75.0 mm in size and originate from Slovakia. Used in crankcase applications, these bearings provide improved engine efficiency by minimizing friction and wear. Dimensions are provided by the supplier and may include packaging dimensions. 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.
