The bearing sleeve with code number H 40002 is a critical component in the Sulzer ASL25 engine, designed to support and align rotating shafts while minimizing friction. This sleeve serves as a protective intermediary between the shaft and housing, absorbing wear and maintaining precision alignment under thermal and mechanical stress. Built with high-performance materials, it plays a vital role in extending the service life of the crankshaft system and ensuring reliable operation, especially in marine or industrial environments where durability is key.
