227PL21858000 MAHLE Connecting Rod Bearing

Designed for use in engine crankcases, this connecting rod bearing from MAHLE ensures reliable operation between the connecting rod and crankshaft. Its function is to minimize friction, preventing metal-to-metal contact and reducing wear on critical engine components. This bearing provides robust durability and optimized performance, which increases the lifespan of the engine. It has dimensions of 42 x 85 x 136 mm, originates from Brazil, and carries the MPN 227PL21858000. 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.
