On-site Inspection of the crankshaft with appropriate Non-Destructive Tests including hardness checking with portable hardness testing equipment, crack detection by Magnetic Particle Test (MPT). The Inspection Reports are prepared.

A new generation in on-site Crankshaft Grinding equipment can machine and polish in one setting itself as there is no need for separate tools for grinding and machining of Crank Pin and Main Journal of Crankshaft.

Onsite Crankshaft Grinding Equipment drastically reduces the setup time & minimizes the possibility of misalignment of Crankshaft & avoiding the need to set it up 2 or 3 times.

We can undertake in situ Crankshaft grinding from CR Pin dia of 50 mm upwards. Special purpose tooling can be designed in case of limitation of working space in the engine block.

In situ Straightening of Crankshaft is undertaken by the pining process, this in situ Crankshaft Repair saves Crankshaft from rejection. Technicians are specially trained for on-site repair of Crankshaft.

Trained, experienced engineers and mechanics skilled in the art of in situ crankshaft grinding execute the in-situ repair of Crankshaft.


The ready availability of tools and specifications for most engines to execute in-situ crankshaft grinding.


On-site Polishing and Grinding of Crankshaft to remove Bearing line marks and Watermarks.


We take pride in accomplishing grinding of over 10,000 Crankshafts in India and abroad which includes in-situ crankshaft grinding and crankshaft repair in our workshop.

IN SITU REPAIR OF CRANKSHAFT IS UNDERTAKEN FOR FOLLOWING:

Compressor Shafts

Main engine Crankshafts

Auxiliary engine Crankshafts

Cylindrical Shaft and the rotating shaft of mechanical equipment

Turbine and Rotor Shaft
MAIN FEATURES OF CRANKSHAFT GRINDING MACHINE:

Lightweight portable Insitu Crankshaft grinding Machine is used for in situ repairs of Crankshaft.

Tolerance of CR Pin and Main Journal of Crankshaft is maintained strictly as per OEM Specifications.

Technician accompanies with senior engineers to plan and execute the job of Crankshaft Repair onsite.

Portable testing instruments of the latest technology used for on-site inspection of Crankshaft which covers Hardness check, magnetic particle test, deflection of the crankshaft, a dimensional inspection of CR and Main Journal of Crankshaft On-site.

In situ Grinding of Crank Pin & Main Journal of Crankshaft undertaken

Reconditioning of Crankshaft on-site undertaken of all make and model of marine, main and auxiliary engine.


GRINDING OF LARGE CRANK PIN & MAIN JOURNAL DIA OF CRANKSHAFT:

In case of the large diameter of Crankshaft, bearing width and high stock removal from the CR Pin, we suggest the use of in situ grinding equipment which is placed on the fillet radius of the Pin as reference for the grinding stone.

The in situ Crankshaft Grinding machine rotates around the Crank Pin at lower RPM, the grinding is carried out by pneumatic grinder operating with a suitable grinding stone. This process of Reconditioning of Crankshaft is recommended only if the radius profile is not worn out.

Tri metal Bearing | Bimetal Bearings | White Metal Bearings | Engine Bearings Manufacturer

RA Power Solutions understands the importance of   trimetal and bimetal engine bearings   for the main, auxiliary and the various makes and models of the engine in operation for different applications . RA Power Solutions undertakes onsite repair of crankshafts having diameter ranging from 35 to 700 mm for last four decades. Every time the crankshaft is repaired, there is a requirement of undersize bearing. It is our experience that in most of the cases the undersize bearings are not available with the engine manufacturer resulting to the delay in assembly and reconditioning of the engine. The major problem lies with the engines which are old and are no longer manufactured by the companies. In this time of recession , it is not possible for the client to replace the engine with the new one. The cost of bearings offered is also exorbitant. RA Power Solutions plays a very important role as most of the undersize non standard bearing of different make and model of the engines are ...
