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.

The ball bearing with code number K 32388 is a core element in the rotating assembly of the Sulzer ZV40/48 engine, specifically designed to fit into bearing insert K 32332. This high-performance bearing minimizes friction and wear while supporting axial and radial loads during continuous engine operation. Engineered for reliability and precision, it ensures smooth movement within the drive system and contributes significantly to the longevity and performance of the entire mechanical setup.

The sealing component coded K 32394 is designed specifically for the locking screw K 32393 to provide an effective barrier against oil leakage and contamination. In the Sulzer ZV40/48 engine, this seal plays a critical role in maintaining the pressure integrity of the system and protecting internal components from dirt, moisture, and thermal fluctuations. Its precision fit and robust sealing capability support long-term engine efficiency and reduce maintenance requirements.

The locking screw with code number K 32393 is a precision-engineered fastener used to secure cover K 32301 on the Sulzer ZV40/48 diesel engine. Its main function is to maintain a tight and vibration-resistant seal over the barring engine housing, ensuring operational stability and preventing unintentional loosening during engine service. Made from durable, corrosion-resistant materials, this screw is vital for long-term reliability and safety in demanding industrial or marine environments.

The gasket with code 06.56936-2355.0 serves as a vital sealing element within the MAN L21/31 engine, preventing fluid or gas leakage between critical surfaces such as cylinder heads, covers, and manifolds. Engineered from high-temperature and pressure-resistant materials, this gasket plays an essential role in maintaining combustion efficiency, system integrity, and environmental compliance. Its proper fit and function are indispensable for avoiding performance losses and potential mechanical failures.

The screw identified by code number K 33421 serves as a locking component for the serrated bolt-locking device K 33420 in the Sulzer ZV40/48 engine. Though small, this screw is essential in maintaining secure connections under vibration-heavy conditions. By preventing loosening of the bolt-locking mechanism during engine operation, it plays a crucial safety role and ensures mechanical stability, especially in parts of the engine where high-speed rotation and repeated stress cycles are the norm.

The connecting rod shaft, marked with code K 33101, is an integral part of the engine’s powertrain, acting as the central axis around which the connecting rod pivots. This shaft must offer both torsional rigidity and fatigue resistance, as it is continuously subjected to rotational loads and high-frequency vibrations. In the Sulzer ZV40/48, it helps synchronize the movement of pistons with the crankshaft, contributing to engine efficiency and smooth operation across various load conditions.

The connecting rod with code number K 33000 is a key mechanical linkage in the Sulzer ZV40/48 diesel engine, responsible for converting linear motion from the operating piston into rotational motion at the crankshaft. Built to withstand extreme pressure and dynamic forces, this component plays a vital role in maintaining the precision and power transfer within the engine. Its balanced geometry and high-strength material composition ensure smooth operation and long-term reliability, even under the intense thermal and mechanical stress typical of marine diesel engines.

Cylindrical pins with code EN1P1228 are precision alignment elements used throughout the MAN L21/31 engine to ensure the correct positioning of components such as casings, housings, and covers. Manufactured from hardened steel, these pins provide repeatable and stable assembly, reducing mechanical wear and improving servicing accuracy. Their role in maintaining geometric consistency across critical joints makes them vital for the long-term mechanical stability of the engine.
