038NS21975000 MAHLE Camshaft Bearing

Engine Bearings are essential for engine health, as they support the crankshaft and reduce friction during operation. They find application in various engines to maintain performance and longevity. By using these bearings, you can expect improved fuel economy and lower emissions due to reduced energy loss. This MAHLE product (MPN: 038NS21975000) measures 67.0 x 135.0 x 135.0 mm and is produced in Brazil. 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.
