007PS21958050 MAHLE Connecting Rod Bearing Set

MAHLE's Engine Bearings are essential for optimal engine operation, acting as a buffer between the crankshaft and engine block. Found in high-performance engines, they contribute to enhanced reliability. These bearings minimize friction, resulting in better fuel economy and longer component lifespan. 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.
