It is generally observed that in case of failure of crank pin bearing or Main journal bearing, crankshaft loses its alignment. The alignment of crankshaft and its straightness is of great importance. The crankshaft alignment is specified by the manufacturer according to the crankpin diameter,main journal diameter length of crankshaft etc.
In case there is a loss of crankshaft alignment, it is observed that main journal bearings fail repeatedly.
RA Power Solutions Pvt. Ltd. undertakes straightening of crankshaft as per the manufacturer’s specifications onsite by peening process. The technicians are experienced and trained to correct the loss of alignment of crankshaft by peening process. The crankshaft is straightened by peening process to the maximum extent and the final correction is done by grinding of main journals incase required.
