FAQs

1. What is Babbitt bearing repair?

Babbitt bearing repair involves inspecting, cleaning, and restoring worn or damaged Babbitt-lined bearings to extend their operational life. This can include rebabbitting, machining, and final inspection.

2. What is rebabbitting?

Rebabbitting is the process of removing the old or damaged Babbitt metal lining from a bearing shell and replacing it with a new layer. This restores the bearing’s original specifications and performance.

3. Why is rebabbitting important?

Rebabbitting helps in restoring worn bearings without the need for complete replacement. It’s a cost-effective solution that brings back the bearing’s load-carrying capacity and reduces downtime.

4. What types of bearings can be rebabbitted?

Most types of Babbitt-lined bearings, including journal bearings, thrust bearings, and sleeve bearings used in turbines, generators, pumps, and marine engines, can be rebabbitted.

5. How long does the rebabbitting process take?

The timeline depends on the size and condition of the bearing, but typically, the process can take anywhere from a few days to a couple of weeks.

Crankpin | Crankshaft Main Journal Repair and Grinding Machine

Raj — Sat, 09 Apr 2022 05:12:36 +0000

RA Power Solutions has been working on crankshafts for the last further than forty-five years. We undertake crankpin repair, main journal repair, and repair of all types of cylindrical shafts on-site. In addition, we offer these services globally at the client’s location. Furthermore, we provide journal bearing repair and babbitt bearing repair services across the world.

We developed an onsite crankshaft/ crankpin & main journal repair machine twenty years back and our present crankshaft grinding machine ranges from 60 mm to 700 mm in terms of diameter. The crankshaft grinding machine undertakes onsite repair of all popular engines manufactured by reputed companies and installed on vessels, diesel power plants, etc.

Application of Onsite Crankshaft Grinding Machine

A crankshaft grinding machine is designed to undertake repair of all main & auxiliary engines installed on vessels having crankpin/ main journal diameters up to 700 mm in diameter.
Technicians can successfully repair the crankshafts of heavy-duty compressors used in the gas and oil sector. The machine’s design eliminates the need to remove the crankshaft from the compressor casing.
Engineers can repair bearing seating areas of all types of cylindrical shafts onsite without removing them from the equipment.

Design of Crankshaft grinding machine

Technicians can carry the crankpin and main journal repair machine to any site worldwide. Its lightweight design ensures easy transport.
Engineers use titanium alloy to build the machine’s body, ensuring strength for continuous operation in tough conditions.
They design and construct the machine to produce minimal vibration. Remarkably, technicians can even repair the crankshaft while the vessel is sailing. As a result, there is no need to dismantle the engine or bring the vessel to a standstill.
Moreover, they consistently control taper and ovality after grinding the crankpin and main journal within 0.02 mm, ensuring high precision and performance.
The machine achieves a 20 RA surface finish, exceeding engine manufacturers’ standards.
The design of the machine is simple & can be easily operated.

On Site Crankshaft Repair

Training And Operation of Crankshaft Grinding Machine

The training on the operation of crankshaft grinding machine is given in our in-house training school based in IMT Manesar, Gurgaon, India.
We also extend the training to clients at the site free of cost.
The machine is easy to maintain.

Over the years, we have successfully sold more than seventy onsite crankshaft grinding machines worldwide. As a result, we have built strong relationships with shipping companies, diesel power plants, engine repair workshops, and various other industrial clients.

FAQs

1. What kinds of crankshafts can RA Power Solutions repair on-site?

RA Power Solutions can service crankpins and main journals of marine and industrial diesel engines with diameters ranging from 60 mm to 700 mm, without removing the crankshaft from the engine – even onboard operating vessels or at industrial locations

2. Why is in‑situ crankpin and main journal grinding important?

Continuous engine operation can cause taper, ovality, pitting, scoring, or bearing material embedding—issues that degrade performance. Grinding and polishing restore OEM tolerances and a smooth finish, which prevent premature wear and bearing failure

3. How precise is the grinding process?

RA Power Solutions’ machines control taper and ovality within ±0.02 mm, and achieve surface finishes of approximately 20 µin Ra (and polishing standards of <15 µin Ra depending on engine RPM), exceeding typical manufacturer specs

4. Can grinding be performed while the vessel is sailing?

Yes. The precision portable crankshaft grinder, built from titanium alloy for minimal vibration, allows in‑situ grinding and polishing even during vessel operation, speeding up repairs globally

5. What inspection and repair steps are involved?

The procedure includes:
(i) Thorough cleaning and visual inspection
(ii) Crack checks, hardness testing, and dimensional measurement using NDT tools
(iii) Onsite selection and use of appropriate grinding/polishing tools
(iv) Final verification and completion reports by senior technicians.

rebabbitting of white metal bearings

What Are Babbitt Bearings?

Babbitt bearings, also known as white metal bearings, have a soft alloy lining made of tin, antimony, copper, or lead, which provides high load capacity and conformability. These bearings reduce friction and support enormous loads in industrial machinery such as turbines, generators, compressors, engines, and pumps.
