001HL19810000 MAHLE Crankshaft Bearing

MAHLE Engine Bearings are a type of Crankshaft Bearing designed for use in the crankcase of an engine. These bearings are used to support the crankshaft, facilitating smooth rotation and reducing wear on other components. By utilizing MAHLE's Engine Bearings, engine manufacturers can benefit from improved performance, increased fuel efficiency, and enhanced reliability. 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.
