213PL21650000 MAHLE Connecting Rod Bearing

Engine Bearings from MAHLE serve as a critical component in the crankcase of internal combustion engines, facilitating smooth rotation and minimizing damage to surrounding components. Typically used in passenger vehicles and commercial trucks, these bearings offer several technical benefits, including reduced friction and vibration, which contribute to improved fuel efficiency, extended engine lifespan, and superior overall performance. 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.
