The Crankshaft Bearing (BM1125-025) supports the crankshaft for smooth and reliable engine rotation. Replacing worn bearings restores oil pressure and prevents internal engine damage.
A crankshaft bearing is a component installed between the crankshaft and the engine block or connecting rods. Its function is to support the crankshaft, reduce friction, and allow smooth rotation under load.
Key specifications include bearing size (standard or oversize), material composition, clearance tolerance, and compatibility with the engine. It must provide proper lubrication and withstand high loads and temperatures.
Replacement is necessary when the bearing is worn or damaged. Common symptoms include engine knocking, low oil pressure, metal particles in the oil, or reduced engine performance.
