213HL21652000 MAHLE Crankshaft Bearing

Engine Bearings from MAHLE serve as a vital part in the operation of internal combustion engines. Located within the crankcase, they enable smooth rotation of the crankshaft while reducing friction between moving parts. This results in enhanced engine performance and prolonged component life through reduced wear. 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.
