We inspected the crankshaft in detail with dimensional checks, hardness tests, and MPI for cracks and deflection. We found damage on one of the crankpin journals caused by a big-end bearing failure.

Inspection & Diagnosis:

• Taper and ovality in the crankpin is observed as 0.70 mm.
• Due to the failure of the bearing, deep line marks were visible.
• Hardness and MPI tests were done, and no cracks were observed.

RA Power Solutions’ Edge

RA Power Solutions used the latest design of onsite crankshaft grinding machine, having almost no vibrations. The crankpin was undersized by 1.5 mm, maintaining the tolerance within 10 microns. Our technicians took only 18 hours to complete the Crankshaft repair from the time of the start of the preliminary inspection, grinding, and final inspection. The repair of the crankpin in such a short time was possible due to the latest technology, an onsite crankshaft grinding machine, and the experience of our technicians.

What Is Onsite Crankshaft Grinding?

The on site crankshaft grinding machine is manufactured having a range starting from 30 mm to 700 mm in terms of diameter. The smaller diameter of the on site crankshaft grinding machine up to 100 mm is more suitable for grinding and polishing crankshafts used in construction equipment, compressors, pumps, etc.

The crankshaft grinding machine having a range of 100 mm and above is ideal for undertaking crankshaft repair, crankpin grinding, and polishing of marine engines and heavy-duty rotating equipment.

We are the leading provider of onsite crankshaft grinding machines and polishing, Insitu turbine shaft Grinding and Polishing, Rotor Shaft Grinding and Polishing, Portable crankshaft grinding machines, crankshaft grinding and repair.

Key Features of Our Crankshaft Grinding Machines

• Wide diameter range — capable of handling from small shafts (≈ 30-100 mm) used in pumps, compressors, etc., up to heavy crankshafts in marine engines.
• Portable / in-situ design — smaller footprint, easier setup, reduced downtime.
• Durable materials — main structural parts built from titanium / ferrous alloys to handle stress and maintain precision.
• Operator training & support — includes on-site training so technicians can operate and maintain the machine safely and effectively.

Benefits of Choosing On-Site Grinding

Traditional (bench) grinding	OnSite / Portable Grinding
Requires dismantling, transportation	Machine comes to the site, minimal movement
High cost and long downtime	Reduced repair time & costs
Risk of damage during handling	Less handling; safer for crankshaft
Less flexibility for large shafts	Suitable for large & marine-scale jobs

Clients have also noted that with onsite crankshaft grinding, the repair turnaround is much faster, leading to less downtime and lower overall cost.
