Wärtsilä Alternator (Generator) Bearing Rebabbitting & Repair
Wärtsilä alternator and generator bearings are exposed to continuous operating conditions and stresses from load, vibration, heat, and lubrication. The Babbitt white metal lining can wear, score, crack, fatigue, or become damaged over time. When the original shell is suitable for repair, rebabbitting of Wärtsilä alternator bearings is an effective way of restoring the bearing.
RA Power Solutions has over 47 years of experience in Babbitt white metal bearing repair and rebabbitting. Careful inspection, controlled bonding, precision machining, and final dimensional checks are performed to restore the bearing for reliable service.
Wartsila Alternator Bearing Repair Procedure
Before rebabbitting, the bearing is examined carefully to determine the condition of the shell and the existing white metal lining. The damaged Babbitt is all taken out, and the shell is cleaned and fitted for the new lining.
The repair process generally involves:
Removal of damaged Babbitt metal white.
Preparation and cleaning of bearing housing.
Controlled tinning for a good metallurgical bond
High-quality Babbitt white metal die casting.
Precision machining to required dimensions.
Re-establishment of oil grooves and oiling holes.
Final inspection and dimensional check.

Bonding of Quality Babbitt White Metal
The quality of the Babbitt alloy directly affects the bearing performance and the service life. Good wear resistance, fatigue resistance, conformability, and reliable performance under continuous loading are the features of a suitable Babbitt material.
The bond between the Babbitt liner and the steel bearing shell is no less important. The shell is properly prepared for tinning and casting. Before machining, the finished bearing is checked for bonding defects, cracks, porosity, or separation.
Bearing Clearance and Precision Machining
The bearing is then rebabbited and machined to the required dimensions and clearances accurately. Carefully check the internal diameter, roundness, bearing crush, housing fit, and alignment.
The proper surface finish and bearing clearance maintain a stable hydrodynamic oil film. Incorrect clearance results in higher temperatures, wear, vibration, and early bearing failure.

Why You Should Choose Professional Bearing Rebabbitting
The timely repair of bearings can prevent further damage to the shaft journal and other rotating parts. Rebabbitting is a cost-effective option to replace the entire bearing, particularly when the original shell is in good condition.
