007PS21958000 MAHLE Connecting Rod Bearing Set

Engine Bearings from MAHLE serve as a vital link between the crankshaft and engine block, facilitating smooth rotation and reducing wear on other components. These bearings are commonly found in high-performance engines, where their ability to withstand extreme temperatures and pressures is essential. By minimizing friction and maximizing oil retention, these bearings contribute to improved engine reliability and fuel efficiency. 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.
