For almost 45 years, we have provided on site crankshaft grinding services, onsite crankshaft repair, crankshaft reconditioning, crankpin reconditioning, and marine crankshaft repair. Our engineers have received training in crankshaft production facilities in Europe and the United States, as well as crankshaft grinding services.
Most often, the seizure of the bearing causes the crankshaft to lose its alignment and develop a bend. Maintaining the alignment of the crankshaft is crucial during both machining and grinding processes.
On site Crankshaft Grinding and Straightening
RA Power Solutions undertakes the straightening of crankshafts onsite irrespective of the length of the crankshaft, the diameter of CR pin, and the main journal.
Our trained technicians straighten the crankshaft using the peening procedure. We’ve completed numerous projects involving crankshaft straightening and onsite grinding of crankshafts across various engine setups.
At RA Power, precision crankshaft grinding is our specialty. First, we focus on restoring the crankshaft’s functionality and structural integrity for automotive, marine, and industrial applications. Additionally, our advanced equipment and skilled team ensure top-tier accuracy and an ultra-smooth surface finish. As a result, the crankshaft’s lifespan and overall performance improve significantly.
Our specialized team uses advanced machinery to restore your crankshafts precisely to their original specifications.
RA Power Solutions has recently supplied a crankshaft grinding machine ranging from 220 to 260 mm in diameter to a Bangladesh-based client. This is the first onsite crankshaft grinding machine to be sold in Bangladesh.
Our technicians use the pinning process to straighten the crankshaft in situ, preventing crankshaft rejection and eliminating the need for replacement. They are specially trained to perform crankshaft repairs directly on-site.

FAQ
We repair the crankshaft right where it is using in-situ grinding, so the engine stays in place and there’s no need to remove or ship the crankshaft off-site. This approach saves a ton of time and cuts costs big-time.
We can grind and repair crankshafts up to 700 mm in diameter, covering a wide range of main and auxiliary engines, marine and industrial alike.
Because we perform the work onsite, we eliminate engine dismantling, crankshaft transportation, and unnecessary operational downtime. This directly cuts downtime and reduces logistics and repair costs.
The service uses specialist equipment and highly trained technicians to restore journals, alignments, tolerances, and polish surfaces back to near-OEM spec (including taper/ovality correction, surface finish improvements).
Yes—it’s designed for marine vessels (even while sailing), land-based power plants, and industrial sites worldwide. The tech and team are deployed globally.
