We extend professional services for the repair of old bearings up to 1500 mm in diameter. All the bearings are rebabbitted by centrifugal casting. The approved procedure for remetalling white metal bearings is followed the gist of which is as follows:-
PROCEDURE FOR REBABBITTING OF OLD BEARINGS:-
- Removal of old white metal from steel casing under the regulated temperature.
- Inspection of a crack in steel casing or bearing after removal of Babbitt white metal.
- The crack detection is done by MPI and dye-penetrant test.
- We give great importance to shot blasting/sandblasting of steel casing. This is done in the special-purpose shot blasting machines.
- Checking the hardness of the steel casing and again checking for cracks after the shot blasting process.
- Selection of a high grade of Babbitt metal, we prefer the use of a higher grade of Babbitt metal than the existing one to enhance the life of bearings.
- Centrifugal casting of Babbitt white metal.
- Inspection of bonding of Babbitt white metal with steel casing by ultrasonic and dye-penetrant test.
- Rough machining, final machining, and maintenance of tolerances strictly as per the drawing on CNC machines supported with DRDO.
- Final inspection and preparation of reports.
THE REBABBITTING OF OLD BEARINGS AND MAINTENANCE OF BEARINGS IS UNDERTAKEN FOR THE FOLLOWING:-
The most highly recommended repair procedure for large steam and hydro turbine generator equipment. Centrifugal casting is the method used to obtain maximum bond strength in the recasting process of Babbitt bearings. Other casting methods (Static casting, TIG and Puddling, and Metalizing) are also available for:
- Fan Bearings
- Motor Bearings
- Ball Mill Bearings
- Tilt Pad Bearings
- Thrust Shoes
- Pillow Blocks
- Hydrogen Seals
- Engine bearings comprising main and crankpin bearings
- Alternator bearings for high-capacity engines, turbines, rotors, and various applications.
