We provide crankshaft grinding services, repair, and overall maintenance of auxiliary and main engines installed on vessels. We also extend these services to high-capacity power plants spread all over the world.

While standard-size bearings are readily available in stock with engine manufacturers, we have experienced that most of the time it is difficult to obtain tri-metal bearings for the crankpin and main journal of the crankshaft in undersized.
