Wartsila B35:40V20AG2 (9.4 MW) | Alternator/Generator Bearing | Rebabbitting & Repair | White Metal
RA Power Solutions was approached by a power generation company based in Yekaterinburg, Russia, for the urgent repair and rebabbitting of Wärtsilä B35:40V20AG2 (9.4 MW) alternator/generator bearings.
The generator bearings were air-freighted to our Gurgaon facility for repair. The main dimensions of the generator bearings are as follows:

Pre-Inspection of Alternator/Generator Bearings of Wartsila B35:40V20AG2 (9.4 MW)
The alternator/generator bearings were thoroughly inspected and prepared in compliance with established engineering procedures prior to starting the rebabbitting operation.
i) The inner diameter (ID) of the bearings was completely cleaned, and the damaged white metal lining was removed.
ii) To provide a clean surface for rebabbitting, the bearing shells were shot blasted to eliminate oxidation, impurities, and leftover babbitt.
iii) To find any cracks or flaws, hardness testing and magnetic particle inspection (MPI) were performed. The findings of the inspection were determined to be within reasonable bounds.
iv) Using cutting-edge centrifugal casting machinery, the alternator/generator bearings were rebabbitted at our Gurgaon facility. In order to strictly adhere to the client's drawings and the original manufacturer's specifications, the new white metal lining was cast and then precision machined to retain the inner diameter (ID) and bearing clearances.

Procedures Adopted for the Rebabbitting of Alternator/Generator Bearings of Wärtsilä B35:40V20AG2 (9.4 MW)
a) The bearings' white metal was eliminated. To ascertain the grade of the metal utilised, a metallurgical test was carried out. It was made sure that the white metal utilised for rebabbitting was either the same quality or a greater grade than what was initially found in the bearings.
b) We solely imported premium white metal from a top Spanish manufacturer.
c) The alternator/generator bearing shells were sandblasted after the white metal was removed to reveal the base metal and produce an appropriate surface profile, guaranteeing a strong bond between the base metal and the new Babbitt liner.
d) To find any cracks, Magnetic Particle Inspection (MPI) was performed. Our experience has shown that accidents or unusual spikes in operation temperature might cause cracks to form.
e) The alternator/generator bearings' inner diameter (ID) hardness was examined. The "scooping" method or localised grinding were used to eliminate any hard places that were found.
f) A centrifugal casting technology was used for rebabbitting, guaranteeing a consistent white metal lining with appropriate metallurgical bonding.
g) Before being delivered, the Babbitt surfaces underwent precise machining, mirror polishing, and the application of a protective wax coating.
h) Ultrasonic testing (UT) was done to look for any internal flaws or irregularities following rebabbitting.
The alternator/generator bearings of Wärtsilä B35:40V20AG2 (9.4 MW) were rebabbitted using these techniques, guaranteeing excellent metallurgical bonding, dimensional precision, dependable performance, and a prolonged service life under difficult operating conditions.

White metal lining fatigue
Taper and ovality development
Misalignment of the rotor shaft
Low pressure of lubricating oil
obstructed lubrication channels
Contamination of oil
Overheating during operation
unbalance in the rotor
Distortion of the foundation or bedplate
