In olden times, whenever the crankpin or main journal of the crankshaft was damaged due to bearing failure or any other reason, the crankshaft was removed from the engine block by disassembly of the complete engine, packed, and taken to the workshop for grinding on a stationary crankshaft grinding machine.

Introduction of On Site Machining Tools:

With the introduction of an onsite machining tool, it is possible to undertake the repair of the crankpin and main journal. RA Power Solutions undertakes onsite grinding of crankshaft and main journal of the diameter ranging from 35 mm to 700 mm. The repair is possible without disassembling the engine, and there is no need for the removal of the crankshaft. The portable and lightweight crankshaft machining tool is inserted from the window for grinding and polishing.

Why This Technology Stands Out

The following are the advantages of using RA Power Solutions’ in situ grinding crankpins services:

• Experienced technicians to assess the fault in the crankshaft and plan the repairs.
• The latest design of portable crankshaft grinding tools ranges from 35 to 700 mm.
• The lightweight machine can travel as accompanied baggage by air to any part of the world.
• Our crankshaft grinding machine weighs 1/3rd of our competitors saving on freight costs.
• RA Power Solutions is the world’s largest manufacturer of portable in situ crankshaft grinding. machines having sold more than 80 crankshaft grinding machines all over the world. Technicians can modify and manufacture the dedicated machine according to the space available at the site.
• Minimum repair time and cost of downtime are reduced considerably.
• A company having more than forty- five years of experience.
• The latest breed of inspection instruments is available to undertake hardness tests, MPI, surface roughness tests, dimensional inspection, etc.
• We are a New Delhi-based company and offer rates that are considerably lower than European companies.

Real-World Success: Grinding Underway at Sea

RA Power Solutions accomplished a remarkable offshore repair on a MAN B&W 6L 28/32H crankshaft during a vessel’s voyage from Cape Town to India. Their technicians:

• Measured each crankpin’s taper, ovality, and hardness.
• Used MPI to inspect for cracks (none found).
• Re-grinded all crankpins by 0.5 mm (from 230 mm to 229.50 mm).
• Delivered tolerance results within 0.03 mm accuracy—all while the ship was sailing.

We also manufacture them from samples of equipment when the original manufacturer no longer produces the bearings.  They follow stringent quality control norms during manufacturing. We use a centrifugal system for rebabbitting white metal, which ensures excellent bonding between the base metal and white metal.

The white metal after centrifugal casting has a dense surface without any pin holes or blow holes, which results in satisfactory performance and long life of the white metal babbitt bearing.

 RA Power Solutions uses our in-house, latest-design equipment for rough and final machining and to maintain critical dimensions. We manufacture white metal babbitt bearings as per international standards and maintain close tolerances. We have the facility to manufacture white metal babbitt bearings up to the outer diameter of 1500 mm.

Rebabbitting of old white metal bearings is undertaken, which develops taper and ovality or gets damaged. We are exporting bearings regularly to Singapore, Indonesia, Nigeria, the UK, South America, Sri Lanka, Greece, Dubai, Qatar, etc.

Babbitt Metal Supplier | White Metal Babbitt Manufacturer

Manufacturers of non-ferrous metals such as tin, lead, copper, antimony, zinc, and aluminium produce white metal for the heavy-duty engineering industry, diesel engines, turbines, and alternators. The tin-based Babbitt white metal manufactured qualifies ASTM, SAE, and federal specifications of Babbitt metal. Being an ISO 900:2015 certified company, we provide detailed metallurgical analysis reports with the Babbitt white metal manufactured and supplied by us. The quality of the white metal is assured and guaranteed.

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.

RA Power Solutions has four decades of experience in working on crankshafts of high-capacity main and auxiliary engines. Factory training prepares our technicians to repair crankshafts. They strictly follow the manufacturer’s specifications and tolerances.
