Few years back no one believed that the crankshafts, crankpin and main journal can be polished onsite by the end user. Always the impression was given by few companies based in Europe and Singapore that crankshaft polishing needs special heavy equipments and technicians with years of experience to undertake the polishing of crankshaft, crankpin and main journal.

RA Power Solutions Pvt. Ltd. manufactures easy to operate and do it yourself crankshaft polishing machines upto 700 mm diameter.

Reason for periodical polishing of crankpin and main journal:-

• The engines of leading manufacturers like Wartsila, Daihatsu, Mirrless Blackstone, Yanmar, Allen, MAK, MAN, B&W, Sulzer, Caterpillar are designed to have close tolerances in the crank pin and main journal.
• Generally, the tolerance ranges between 0.02 mm to 0.05 mm.
• Periodical polishing of crankpin and main journal is highly recommended to remove the linemarks, pitting from the journals.
• Crankshaft polishing improves the surface finish and enhances the life of bearing manifolds.
• The chance of crankshaft meeting with any serious accidents or bearing seizure incidents are reduced considerably.
• The high surface finish of crankpin and main journal after polishing can produce more power, durable and long-lasting performance of Engine.
• The crankshaft polishing results in less noise, vibrations, friction and consumes less fuel.
• Lower emissions are produced.

Due to above and many reasons, it is highly recommended to undertake polishing of crankpin and main journal periodically at the time of major overhauling or replacement of bearings.
