Bearing Sleeve (Code H 40002)

Written by

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.

Cylindrical pins, code EN1P1228, are precision alignment tools used throughout the MAN L21/31 engine to ensure accurate positioning of components such as housings, covers, and structural subassemblies. These hardened steel pins are essential for maintaining mechanical alignment, preventing rotational slip, and ensuring consistent load distribution across connected parts. By securing the geometry of critical interfaces, cylindrical pins play a vital role in minimizing wear and maintaining the long-term reliability of the engine.

MAN L21/31; PLUG SCREWS (Code EN47AR36)

Written by

Plug screws under code EN47AR36 are specially designed fasteners used in various MAN L21/31 engine applications to seal threaded ports, inspection holes, or auxiliary component openings. These screws ensure secure closures that withstand pressure and thermal stress while also allowing maintenance access when needed. Made from corrosion-resistant materials and manufactured with precision threads, plug screws contribute to the engine’s reliability and help prevent fluid leaks or contamination.

The seal ring with code 06.56200-0724.0 is a critical component for maintaining airtight and leak-proof connections within the MAN L21/31 engine. Typically used in high-pressure areas such as cylinder interfaces or fluid line couplings, the seal ring prevents the escape of oil, coolant, or combustion gases. Its resistance to heat, pressure, and chemical corrosion makes it essential for maintaining system integrity and ensuring long-term operational efficiency and safety in demanding marine or industrial environments.
