As a marine engine and mechanical equipment repair company serving industries & shipping companies all over the world for the last 44 years, we understand the importance of the availability of not only high-quality Tri-metal and Bi-metal Bearings but the importance of delivery of bearings on time. During our experience of the last four decades, we have observed that although the crankshaft of the marine engine, compressor, or any rotating equipment is repaired due to the non-availability of the crankpin & main journal bearing engine cannot be put back into operation thus causing losses to the owner.
The non-availability of engine & compressor bearings may be because the equipment is outdated and no longer manufactured by the original equipment manufacturer. There are a number of marine engines, diesel generating sets, and compressors in operation on vessels or industries, the manufacturing of which has been discontinued due to either the closure of the manufacturing unit or the equipment becoming absolute.
RA Power Solutions plays an important role in the manufacturing of marine engines, white metal bearing repair, diesel generators, compressors, and Rotating equipment bearing Tri-metal and Bi-metal.
CKD Skoda Bearing
Tri-Metal Bearing and Bi-Metal Bearing Manufacturer
We have the Principles based in the UK, Europe, and Japan from where we source the Tri-Metal Bearing, The Bi metal Bearings, and Babbitt white metal bearings up to 1500 mm diameter are manufactured in-house.
In case your Engine model is old and is no longer manufactured by the manufacturer, RA Power Solutions can help you in the development & manufacturing of Tri-metal and bi-metal bearings strictly as per the drawing provided by you. We also develop and manufacture Tri-metal & Bi-metal Bearing as per the sample provided by the client.
Tri-metal Bearing for crankpin/main journal ready for dispatch
Manufacturing of standard and non-standard tri-metal bearings and bi-metal Bearing for marine engine and compressor
As a crankshaft repair company, we have observed that due to serious accidents, the damage to the crankpin/ main journal is much more than the last limit of undersize recommended by the manufacturer. In this case, the engine manufacturer refuses to supply the under-size and oversize bearings.
For example, in case of the last limit of Daihatsu crankpin having a standard diameter of 170 mm and after grinding the size obtained is 167 mm, we manufacture the bearing of 3.0 mm undersize and put the engine back into operation on other hand as per the manufacturer of the engine, the crankshaft cannot be used and is rejected.
We have saved hundreds of crankshafts by supplying undersize Tri-metal Bearings and Bi-metal Bearings beyond the last limit of grinding recommended by the engine manufacturer. We regularly supply engine bearings for crankpins, Tri-metal Bearings, engine tri-metal bearings, and Bi-metal Bearing for all make & models of engines like Wartsila, MAK, MAN B&W, Yanmar, Daihatsu, Himsen, Caterpillar, Bergen, Deutz, etc.
Daihatsu crankpin & main journal bearing
We have been regularly exporting the bearings to Bahrain, Bangladesh, Bhutan, Brunei, Burma, Cambodia, East Timor, Georgia, Hong Kong, India, Indonesia, Iran, Iraq, Israel, Japan, Jordan, Kazakhstan, Kuwait, Kyrgyzstan, Laos, Lebanon, Malaysia, Mongolia, Nepal, North Korea, Oman, Papua New Guinea, Philippines, Qatar, etc.

The following are the common problems observed in compressor crankshafts :
Excessive wear and tear of crank pin and main journal.
Increase of oil gap between the crank pin, main journal, and bearing.
Frequent damage to crank pin and main journal bearings due to the development of excessive taper and ovality.
Seizure of crank pin and main journal bearings on compressor crankshaft due to non-replacement of bearings within the specified schedule.
Development of rough surface of crankpin and main journal due to bad quality of lubricating oil and lubricating oil filters.
Damage to both sides of the radius fillet due to an accident.
Damage to crank pin of compressor crankshaft due to excessive ovality in connecting rod big end bore.
With the introduction of the latest technology, there is no requirement to dismantle the crankshaft from the compressor casing.
Our technicians visit the site and undertake on site compressor crankshaft inspection. We have on-site compressor crankshaft polishing and grinding equipment available which is carried by our technicians and repairs are undertaken in no time.
SAVE YOUR COMPRESSOR CRANKSHAFT AND INCREASE THE LIFE:-

White Metal Babbitt was introduced about 180 years back and over the time, it has been improved with presence of tin, copper and antimony. Lead can be sometimes added in place of the tin.
RA Power Solutions manufactures white metal/ Babbitt white metal alloy according to international norms or as per the customized requirement of Babbitt white metal of the client.
THE MAIN ADVANTAGES OF WHITE METAL/ BABBITT WHITE METAL ALLOY:-
White metal has lower wear.
High friction resistance.
Corrosion resistance.
Hard/soft composition of white metal.
Better absorption of lubricant and foreign particles.
Considering the few of the inherent properties of white metal and Babbitt white metal alloy mentioned above, it has various applications.
APPLICATIONS OF WHITE METAL/ BABBITT WHITE METAL ALLOY:-
Babbitt white metal is used as lining for bearing shells which are made out of cast iron, bronze or steel.
The Babbitt lining of bearing helps in preventing friction and wear which enhances the life of the bearing manifolds.
Babbitt metal is preferred for steady load conditions with application for electrical motor, pumps, blowers, turbines, engines, compressors, etc.
We are the largest manufacturer of Babbitt metal, Babbitt white metal, and babbitting alloy metal all over the world including Greece, Moldova, Belarus, Australia, Austria, Belgium, Brazil, Singapore, Dubai, Greece, Cambodia, Colombia, Denmark, Ethiopia, Ghana, Nigeria, Sri Lanka, etc.
