Onsite Crankshaft Grinding Machines – Worldwide Supplier

Onsite crankshaft grinding machine is a specialised machine that is used to manufacture, repair, and recondition crankshafts on site. The engine’s backbone is the crankshaft, which converts piston motion into rotation. Consequently, its precision is essential. Crankshafts can develop surface imperfections, erosion, or scoring over time. Through the restoration of engines to their exact proportions with a faultless finish, our machine guarantees their dependability and efficiency.

RA Power Solutions is emerging as a worldwide supplier of such machines, enabling engine and repair shops, power plants, and marine operators to carry out crankshaft repairs without removing them from the engine block.

Onsite Crankshaft Grinding in Singapore

Singapore, being one of the world’s busiest maritime hubs, demands engine components that perform flawlessly even under the harshest conditions. When a crankshaft develops wear, taper, ovality, or damage, traditional repair often requires removing the engine components, incurring heavy transport expenses, and resulting in costly downtime. In situ crankshaft grinding, also known as onsite crankshaft grinding, offers a smarter alternative. At RA Power Solutions, we specialize in insitu crankshaft grinding and crankshaft repair, delivering high precision, minimal disruption, and cost-effective solutions in Singapore.

What Is Onsite Crankshaft Grinding and Repair?

In situ crankshaft grinding means repairing the crankshaft’s main journals or crankpins without dismantling the engine or removing the crankshaft from its block. By using portable grinding and polishing machines, technicians restore worn or damaged surfaces to OEM standards. Crankshaft repair in this context encompasses grinding, polishing, inspection, and, if necessary, reconditioning of the crankshaft, all performed directly onsite.
