Why Rebabbitting Is Important

Rebabbitting brings a damaged or worn bearing back to OEM-level efficiency by restoring:

• Correct bearing geometry
• Load-carrying capacity
• Lubrication flow
• Vibration and heat control

Signs Your Bearing Needs Rebabbitting

If you notice any of these issues, the bearing likely needs immediate inspection or rebabbitting:

• Wear marks or uneven surfaces
• Scoring, pitting, or blistering
• Burn marks or discoloration
• Lubrication breakdown
• Excess vibration or noise

These symptoms often indicate deeper problems in the shaft line or lubrication system, so early diagnosis is crucial.

How Rebabbitting Is Done

Inspection & Non-Destructive Testing

Technicians inspect the bearing for cracks, alignment issues, and material fatigue.

1. Old Babbitt Removal
   They melt or machine off the worn Babbitt layer from the shell.
2. Surface Preparation
   They clean, tin, and prep the shell to ensure a strong bond.
3. New Babbitt Casting
   High-grade babbitt metal—typically tin-based—is poured or centrifugally cast.
4. Machining to OEM Specs
   They bore, chamfer, and finish the new Babbitt surface to precise OEM tolerances.
5. Final QA & Clearance Check
   The bearing is tested for geometry, hardness, bond strength, and fit.

Why Babbitt Metal Is Used

Babbitt works as a soft, protective layer that:

• Embeds contaminants (protecting the shaft)
• Supports hydrodynamic lubrication
• Reduces friction and heat
• Prevents catastrophic damage during overloads

The post What Is Rebabbitting of a Bearing? appeared first on Rebabbitting Bearing.

RA Power Solutions undertakes Rebabbitting of Babbitt white metal bearings for last more than 45 years of thrust, crankpin, and main journal, turbine, rotor, and alternator bearings for all applications up to 1500 mm diameter.

At RA Power Solutions, we take pride in our expertise as a turbine journal bearing manufacturer and our ability to provide exceptional repair services for Babbitt white metal bearings.

In this blog post, we highlight our recent accomplishment in Nigeria, where we successfully repaired a 120 MW turbine bearing. Our team of highly skilled technicians and advanced facilities enabled us to overcome the challenges and restore the bearing’s functionality efficiently.

Read on to learn more about our expertise as a turbine journal bearing manufacturers, turbine bearing repair of 120 MW, and how we handled this complex repair project.

OUR EXPERIENCE IN REBABBITTING OF WHITE METAL BEARING:-

• Extending the services of Rebabbitting and repair of white metal bearings all over the world for more than 45 years.
• We strictly perform the rebabbitting of Babbitt white metal bearings up to 1500 mm using the centrifugal process, ensuring a strong bond between the Babbitt white metal and the steel base of the bearing.
• In-house machining facilities with an accuracy of 10-20 microns are achieved.
• Regularly undertaking Rebabbitting assignments of prestigious organizations from the field of nuclear power stations, high-capacity turbines and generators, and main and auxiliary engines.
• Facilities for metallurgical analysis of Babbitt white metal and expert recommendation for enhancing the quality of Babbitt white metal for an increase in service life.
• All bearings are subject to strict quality control norms by experienced technicians for hardness tests, crack checks by MPI, dimensional checks, and ultrasound for bonding.

REPAIR OF 120 MW TURBINE BEARING UNDERTAKEN FOR A LEADING NIGERIAN STEEL COMPANY:-

A leading steel company based in Nigeria approached us to rebabbitt a white metal turbine bearing with a capacity of 120 MW. They had previously relied on a European company for the repairs, but those bearings failed after a short period, delivered unsatisfactory performance, and came at an exorbitant cost.

RA Power Solutions undertook the successful repair of rebabbitting of the 120 MW turbine bearing.

THE DETAILED MAIN DIMENSIONS OF THE TURBINE BEARING ARE MENTIONED BELOW:

Upon receiving the bearing from Nigeria, we thoroughly inspected it for the following:

• We removed the old white Babbitt metal under controlled temperature conditions.
• We performed shot blasting on the bearing shell.
• We checked the hardness of the inner diameter.
• We performed crack detection on the bearing steel casing using MPI and dye-penetration tests.
• We conducted crack detection tests using the ultrasound method both before and after rebabbitting.
• We conducted ultrasound testing again to check the bonding between the Babbitt white metal and the steel casing.
• Assistance was provided in the transportation of heavy bearings to our works for white metal rebabbitting from other countries.
• We provide complete assistance in the export of damaged bearings and return of bearings to the end-user after turbine bearing repair.
• We have a definite advantage of our location as we are only 30 30-minute drive from New Delhi International Airport.
• Our plant is also close to the dry port of New Delhi, in case our client wants to dispatch the bearing by sea.

We provided emergency services for the repair of the white metal bearing.

Following are the main observations:-

Turbine bearing inspection

• The turbine bearing was removed from the shaft, and it was observed that the white metal from the bearing was partially removed.
• Heat exposed a portion of the turbine bearing, turning it a blackish colour.
• Deep bearing line marks appeared on the rest of the bearing’s inner diameter.

Observations on turbine shaft:-

• We calibrated the turbine shaft and observed that the dimensions, taper, and ovality were within the limits specified in the manufacturer’s manual.
• We noticed line marks on the turbine shaft bearing sitting area.
• We checked the surface finish of the turbine shaft and bearing sitting area and found it rough.
