 
                A few years ago, no one believed that end users could polish crankshafts, crankpins, and main journals onsite. Companies based in Europe and Singapore created the impression that crankshaft polishing required special heavy equipment and highly experienced technicians to perform the job.
Crankpin Machining is Required in Case of the Following Damage to the Crankpin
- Development of excessive taper & ovality on a crankpin.Seizure of crankpin bearingDevelopment of bearing marks and pitting on crankpin.
- Development of excessive taper & ovality on a Crankpin diameter.
- Seizure of crankpin bearing.
- Development of bearing marks and pitting on the crankpin.
- Due to the above defects, it is necessary to get the Crankpin Machining undertaken.

RA Power Solutions Pvt. Ltd, an easy-to-operate and do-it-yourself crankshaft polishing machine manufacturer, up to 700 mm in diameter.
Reason for periodical polishing of crankpin and main journal:-
- 
Leading manufacturers like Wartsila, Daihatsu, Mirrlees Blackstone, Yanmar, Allen, MAK, MAN, B&W, Sulzer, and Caterpillar design their engines with close tolerances in the crank pin and main journal. 
- Generally, the tolerance ranges between 0.02 mm to 0.05 mm.
- We highly recommend polishing the crankpin and main journal diameters periodically. This process removes line marks and pitting from the journals.
- Crankshaft polishing improves the surface finish and enhances the life of bearing manifolds.
- 
Proper maintenance and precision machining greatly reduce the chances of serious crankshaft accidents or bearing seizure incidents. 
- The high surface finish of the crankpin and main journal after polishing can produce more power, durability, and long-lasting performance of the Engine.
- The crankshaft polishing results in less noise, vibrations, and friction, and consumes less fuel.
- Lower emissions are produced.

Due to the above and many other reasons, it is highly recommended to undertake the polishing of the crankpin and main journal periodically at the time of major overhauling or replacement of bearings.
RA Power Solutions Pvt. Ltd. manufactures, for the last forty-five years, revolutionary equipment for the onsite polishing of crankpins without removing the crankshaft from the engine block. The crankshaft polishing machine is manufactured in the range starting from 35 mm to 700 mm in terms of diameter.
RA Power Solutions has the following features:-
- The technician inserts the crankshaft polishing machine through the engine block inspection window. It sits directly on the crankpin diameter.
- There is no requirement for the removal of the crankshaft from the block.
- The machine supplied in two versions: electrical and pneumatic. This depends on the availability of the facilities on board the vessel or in any industry.
- Machine is easy to operate, and can reduce the taper and ovality. To improve the surface finish to far better than the international standards.
- Any technician can easily operate the crankshaft polishing machine. The machine allows them to perform polishing efficiently.
