Engine Bearings For Crankpin and Main Journal
Engine bearings manufactured from tri-metal for the crankpin and main journal of the crankshaft are supplied by RA Power Solutions.
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.
Requirement of Undersized Tri-Metal Bearings for Crankshaft
After grinding of the crankpin and main journal of the crankshaft, there is a requirement for undersized bearings, which are, in most cases, not readily available.
RA Power Solutions is the largest exporter of tri-metal bearings, mainly for diesel engines. We are listing below the names of a few popular engines and their models for which we maintain a ready stock of the bearings.
