When a crankshaft fails or journals wear beyond tolerance, downtime costs can rise rapidly. RA Power Solutions delivers fast, reliable onsite crankshaft grinding and insitu crankshaft grinding services across India—restoring main journals and crankpins to OEM specifications without removing heavy components or taking engines to remote workshops. Our experienced teams, bespoke portable grinding machines, and class-approved procedures minimize downtime and get vessels, power plants, and industrial units back to work quickly.

Why Choose In-Situ/Onsite Crankshaft Grinding?

Unlike workshop-only repairs, insitu crankshaft grinding (grinding done in place) removes the logistical delays, transport risks, and high costs associated with dismantling and shipping large crankshafts.
R A Power Solutions combines decades of field experience with vibration-free, portable grinding machines to deliver:

Precision grinding and polishing to OEM tolerances
Minimal downtime—repairs are typically performed on site, often while the asset is in port or at the plant.
Full inspection, MPI, and metallurgical options (hardness tests, crack detection, and rebabbitting) were required.
