The bearing bush K 71018 is a precision sliding bearing element installed within the oil pump casing and bearing cover of the Sulzer ZV40/48 engine, providing a low-friction support surface for rotating shafts. Designed to maintain accurate alignment and stable operation under continuous load, it reduces wear and ensures smooth rotational motion within the pump assembly. Manufactured from high-quality bearing materials with optimized lubrication characteristics, this bush effectively absorbs vibrations and distributes loads evenly. By maintaining consistent clearances and minimizing frictional losses, the K 71018 bearing bush plays a crucial role in enhancing oil pump efficiency, extending component life, and ensuring reliable engine lubrication performance.
