Babbitting Services for Old Bearings | Manufacturing of New Babbitt Bearings

Raj — Tue, 23 Mar 2021 05:40:42 +0000

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.
Technicians detect cracks using MPI and dye-penetrant tests.
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.

We undertake the rebabbitting and maintenance of old bearings for the following:

The most highly recommended repair procedure for large steam and hydro turbine generator equipment.

To obtain maximum bond strength in the recasting process of Babbitt bearings, engineers therefore use the centrifugal casting method, as it ensures a superior metallurgical bond and consistent quality.

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 application

Turbine White Metal Bearing – RA Power Solutions

Raj — Thu, 08 Sep 2016 11:14:25 +0000

Turbine white metal bearings are required for industrial turbines to operate smoothly and reliably. These bearings, which are designed to sustain high radial and axial loads, reduce friction between rotating components and their housings, resulting in efficient operation and a long service life.

At RA Power Solutions, we specialise in the manufacturing of new white metal bearings as well as expert rebabbitting and repair services for bearings that have worn out during operation.

What Are Turbine White Metal Bearings?

White metal bearings, also known as Babbitt bearings, are manufactured out of a soft alloy lining (usually tin, antimony, or copper) that is bonded to a steel backing. This combination results in an excellent surface that decreases friction while resisting wear at high loads and speeds.

These bearings sustain the rotating shaft in turbine applications while reducing heat generation and vibration, making them critical components in power plants and heavy equipment.

The base metal on which the babbitting of the white metal bearing is carry out must be free from cracks and hard spots. To achieve strong bonding between the Babbitt white metal and the base lining, manufacturers prefer the centrifugal casting process. This process ensures a uniform layer of Babbitt white metal with a dense and consistent microstructure.

Advantages of Turbine White Metal Bearings

Industrial white metal bearings offer several key benefits:

Low friction and wear resistance, ensuring smooth shaft rotation.
Shock and vibration absorption increases durability in heavy machinery.
High load capacity and reliability, ideal for turbines, generators, and large engines.
Custom manufacturing & repair, tailored to specific shaft sizes up to 1500 mm.
Reduced operating costs, rebabbitting old bearings saves money over replacement.

Why Choose RA Power Solutions?

RA Power Solutions Pvt. Ltd. manufactures new white metal Babbitt bearings and carries out rebabbitting of white metal bearings damaged during operation. The company manufactures the bearings according to the turbine shaft sizes obtained after grinding and polishing.

FAQs:

1. What is a turbine white metal bearing?

A turbine white metal bearing is a Babbitt-lined plain bearing that supports turbine shafts, reducing friction and wear under heavy load conditions.

2. How do white metal bearings improve turbine performance?

They reduce friction, dissipate heat efficiently, absorb shocks, and help maintain smooth rotational movement for turbines and other heavy machinery.

3. What is the rebabbitting process?

Rebabbitting involves removing worn white metal and re-casting new Babbitt alloy onto the bearing shell, followed by precision machining and quality checks.

4. What materials are use in white metal bearings?

The bearing alloy typically includes tin, antimony, and copper, balancing low friction with strength and corrosion resistance.

5. Can you manufacture custom white metal bearings?

Yes, bearings can be custom-made as per client requirements and shaft size, up to 1500 mm diameter.
