151HL18607000 MAHLE Crankshaft Bearing

MAHLE's Engine Bearings (MPN: 151HL18607000) play a vital role in an engine's operation, facilitating the rotation of the crankshaft. Typically used in passenger vehicles and industrial equipment engines, these bearings are designed to minimize friction and wear on moving parts, resulting in improved fuel efficiency and extended engine lifespan. Originating from Slovakia, this product measures 81.0 x 37.0 x 60.0 mm. 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.
