Our specialization in Tri Metal Bearing for crank pin/ main journal of marine engine

RA Power is engaged in extending on site crankshaft repair services all over the world for the last more than 41 years.

It is obvious that whenever the grinding of the crank pin & main journal of the diesel engine or compressor crankshaft is undertaken there is a requirement for under size crank pin and main journal bearing.

It is generally observed that in most cases it is difficult to source under-size bearings from the manufacturer of the engine and compressors as they are not available in the stock. The problem arises when there is a requirement for a special size undersize of the bearing.

We have also observed that in the case of an engine make & model which is more than 15 years old it is rather impossible to source the bearing from the manufacturer of the engine as that particular model is discontinued by the manufacturer.

The ship owners or the customers having old models of engines face this problem of nonavailability of crank pin and main journal bearing.

RA Power Solutions plays an important role in arranging the special & under-size bearing according to the dimensions of the crank pin and main journal obtained after grinding.

Broken Engine Block Repair | Damaged Engine Bedplate Repairs | Metal Stitching

The repair of broken engine block, turbocharger casing, and heavy cast iron parts can be successfully repaired by metal stitching, metal locking, and metal surgery process.

The repair of crack and repair of damaged casting by welding process is now completely outdated and is not recommended for repair of damaged cast metal and cast iron parts. In fact, it is observed that in certain cases repair by welding results in more serious damage due to the generation of heat and stress during the process of welding. RA Power Solutions have been undertaking repairs of damaged engine block, steel components repair, cast iron repairs, and all types of cast components by metal stitching and metal locking process for the last four decades.
