081PL21836000 MAHLE Connecting Rod Bearing

MAHLE's Engine Bearings (MPN: 081PL21836000) are precision-engineered for use in connecting rod applications within the crankcase of an engine. Measuring 46.0 x 67.0 x 67.0 mm in size, these bearings are manufactured in Brazil and offer a range of technical benefits, including reduced friction, improved power output, and enhanced fuel efficiency. 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.
