]]> RA Power Solutions Pvt. Ltd. has offered in situ crankshaft repair and polishing services for over four decades. The crankshaft is the most important part for keeping the engine running properly. It is an essential component of engines in marine boats, power plants, and heavy machinery. However, when it becomes damaged or worn out, it can bring operations to a standstill, resulting in costly repairs and downtime. RA Power Solutions, a global pioneer in crankshaft maintenance, has introduced its breakthrough in situ crankshaft grinding technology to Bangladesh. This unique approach is changing the game for industries throughout the country.

With the insitu crankshaft grinding machine, our trained specialists can arrive at a site in the shortest amount of time and fix the crankshaft without removing it from the main engine.

Efficient crankshaft on the engine Restoration: 35 to 700 mm in diameter Grinding Accuracy

Since the crankshaft is the engine’s central component, it transforms reciprocating motion into the linear movement that powers the engine through the use of connecting rods. With the process, technology, and onsite crankshaft grinding equipment from RA Power Solutions, crankshaft repair is now feasible without removing the crankshaft from the engine. These machines range in size from 35 mm to 700 mm. Our technology can repair crankshafts up to 700 mm in diameter, allowing us to fix any crankshaft, regardless of its weight or length.

In general, the crankshaft has several applications, including diesel generators and marine engines. Typical areas of crankshaft applications are as follows:

  • Compressors
  • Power generators
  • Forging hammers
  • Pumps
  • Marine engines

RA Power’s Journal and Crankshaft Machining Advantages:

  • The vast experience of having repaired over 10,000 shafts on any size Main or Auxiliary engine
  • Specially designed crankshaft machining tooling for insitu reconditioning without dismantling the full engine, deployed all around the globe.
  • A large, global team of highly skilled machining technicians ensures a rapid, expert response anytime and anywhere.
  • The latest breed of inspection instruments is available to undertake hardness tests, MPI, surface roughness tests, dimensional inspection, etc.

Giving ship and power plant crews the tools they need to grind and fix crankshafts on site

Years of crankshaft grinding and polishing by RA Power Solutions, it is now possible to not only grind and polish the crankshaft onsite, but also to repair the crankshaft by ship or power plant crew.

FAQs

1. What sizes of crankshafts can you repair onsite?

Customers often want to know the diameter range your equipment handles. RA Power’s insitu grinding is capable of servicing crankpins from 35 mm up to 700 mm (even 50–700 mm) without engine removal.

2. How much downtime and cost savings are involved?

One of the top concerns: how in-situ grinding cuts downtime and expense. By avoiding full engine disassembly and shipping, companies save significantly on labor, transport, and workshop costs.

3. What precision and finish can you achieve?

Customers ask if the onsite process meets OEM specifications. The portable machines deliver precision within 10–25 µm and achieve surface finishes (Ra) that align with OEM standards.

4. Can you repair crankshafts while the engine is in operation or at sea?

A common need in marine and power-plant contexts. Yes—insitu grinding can be done on-vessel (even underway) or at power plants, offering portable, global 24/7 service.

5. What inspection and quality assurance processes do you use?

Customers want confirmation of quality control. Services typically include MPI/crack detection, hardness testing, surface roughness measurement, dimensional checks, vibration testing, ensuring journals are restored to spec.
