87461600 Kolbenschmidt MAIN BRG SET

Kolbenschmidt's Main Bearing Set is a vital part for engine repair and replacement, consisting of bearings that reduce wear on the crankshaft and promote efficient power transmission. This product finds its usage in various industries where engines are subject to heavy loads, including construction equipment and buses. Key technical advantages include increased bearing life, minimized vibration, and optimized performance. 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.
