007PS21958025 MAHLE Connecting Rod Bearing Set

Engine Bearings by MAHLE (MPN: 007PS21958025) are essential for the crankshaft's operation, minimizing wear and tear on engine components. They find application in various engines within vehicles, promoting efficient energy transfer and reduced noise levels. Manufactured in Brazil, these bearings have dimensions of 35.0 x 75.0 x 122.0 mm. 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.
