Engine Bearings For Crankpin and Main Journal

RA Power Solutions supplies engine bearings made from tri-metal for the crankpin and main journal of the crankshaft.

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

While standard-size bearings are readily available from engine manufacturers, we have found that it is often difficult to obtain tri-metal bearings for the crankpin and main journal of the crankshaft in undersized sizes.

Undersized tri-metal bearings are required for the crankshaft.

After grinding the crankpin and main journal of the crankshaft, undersized bearings are required, which are typically difficult to find.

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 bearings.
