On-Site Crankshaft Grinding & Polishing | RA Power Soltions
The reliability of large marine and power-plant engines depends greatly on the condition of the crankshaft. Even minor wear, taper, or ovality can severely affect engine performance, leading to increased vibrations, loss of efficiency, and unexpected breakdowns. To prevent such issues, on-site crankshaft grinding and polishing have become an essential service for operators worldwide.
Recently, a complete in-situ repair operation was carried out on a Sulzer Engine Z 40/48, which required precision grinding and polishing of its 330 mm diameter crankpin. The repair was executed directly on board, eliminating the need to dismantle the engine or transport the crankshaft to a workshop—saving both time and high operational expenses.
