Yanmar Daihatsu MAK MAN and Crankpin Bearings

About Yanmar Daihatsu MAK MAN and Crankpin Bearings

RA Power Solutions maintains stock of standard undersize bearings for crankpin and main journal of crankshaft. The bearing stock is maintained for the leading manufacturer of engines like Yanmar, Daihatsu, MAK, MAN, Crankpin and main journal bearings. We also maintain a stock of bearings for compressors, pumps, industrial high-capacity fans, and other equipment.

We have experienced that in case of damage to the crankshaft, it requires grinding of the crankpin or main journal as per the extent of the damage. The maximum undersize diameter of the crankpin and main journal which can be maintained depends on various factors like make of the engine, model, diameter of the crankpin and main journal, RPM of an engine load capacity, etc.

RA Power Solutions maintains a stock of crankpin and main journal bearings in different step sizes of diameter as recommended by the manufacturers. As a leading crankshaft repair company with more than 43 years of presence in the international market, we have an experience that in most of cases undersize bearings are not available to hold the vessels for a long time.

In order to put back the auxiliary engine into operation immediately after grinding of crankpin and main journal, we in most of the cases sent the bearings along with our crankshaft grinding team. This facilitates the ship staff to bearings immediately after the grinding job is executed by our engineers.

This saves downtime of the engines and there is no need for holding of the vessels. We maintain the stock of the leading engine manufacturer of engines and have the arrangements to dispatch the crank pin and main journal bearing by courier service to any part of the world.

We regularly supply engine bearings for crankpins, tri metal bearings, engine tri metal bearings, bimetal bearings for all makes and models of engines like Wartsila, MAK, MAN B&W, Yanmar, Daihatsu, Himsen, Caterpillar, Bergen, Deutz, etc.

Superior Surface Finish & Durability

Each crankpin bearing boasts a micro-polished surface that minimizes friction, thus enhancing operational smoothness and extending engine component life. The use of a lead bronze alloy with a special overlay improves resistance to wear and corrosion, ensuring reliable marine performance even in harsh, salt-laden environments.


Custom Fit for Marine Engines

These bearings are developed for exact compatibility with Yanmar, Daihatsu, MAK, and MAN marine engines. With customizable bore sizes and precision-ground diameters per OEM specifications, the crankpin bearings guarantee a secure press-fit and reliable matching to a wide range of crankshaft dimensions common to marine diesel engines.


Engineered for Demanding Conditions

Designed to sustain high axial and radial loads under marine operating conditions, these bearings perform efficiently at temperatures up to 120C. Their robust construction and pressure-fed lubrication accommodate strenuous workloads, making them dependable for continuous marine engine operation.
