001HL21886050 MAHLE Crankshaft Bearing

MAHLE's Engine Bearings (MPN: 001HL21886050) are precision-engineered components that play a crucial role in the crankcase of an engine. Originating from Brazil, these bearings measure 43.0 x 93.0 x 141.0 mm and are ideal for engines demanding high performance. Their technical benefits include increased engine lifespan, minimized friction, and optimized power delivery. 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.
