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
