FAQs

1. What are main journal bearings?

Main journal bearings are critical engine components that support the crankshaft and allow it to rotate smoothly within the engine block. They reduce friction and wear between moving metal parts in internal combustion engines.

2. What is the difference between standard and undersize bearings?

First, use standard bearings when the crankshaft and housing dimensions match the original factory specifications. However, when wear or damage requires crankshaft grinding, install undersize bearings, which are thicker and help restore proper operating clearances.

3. Can journal bearings be repaired or rebabbitted?

You can repair worn journal bearings through a process called rebabbitting, where you remove the old babbitt material and replace it with a new layer to restore the bearing to its original specifications and performance.

4. When should undersize journal bearings be used?

Undersize journal bearings are typically used after crankshaft regrinding, which reduces the journal diameter. These bearings compensate for the reduced size and help maintain correct oil clearance and engine performance.

5. What materials are used in manufacturing journal bearings?

Manufacturers commonly make journal bearings from babbitt metal, an alloy known for its excellent anti-friction properties. Other materials include copper-lead alloys, aluminum alloys, and composite materials, depending on the application.

RA Power Solutions manufactures and undertakes repairs of Babbitt white metal bearings ranging in diameter from 60 mm to 1500 mm.

We have manufactured bearings for more than 45 years and supply them to leading companies worldwide. We manufacture the following types of bearings:

THRUST BEARING AND JOURNAL BEARING MANUFACTURING:-

Mechanical tilting pad bearing
Hydroelectrical turbine bearings
Bearings for high-capacity alternators and rotors
Bearings for the crankpin and main journal of diesel engines, compressors, and rotatory equipment.
Thrust bearings

BABBITT WHITE METAL MANUFACTURING PROCESS:-

We manufacture the bearing steel casing from forging or alloy casting, depending on the client’s requirements and application.

We select Babbitt white metal based on our experience, the application, or the client’s specifications.

DRDO-equipped CNC machines machine the bearing shell.
A centrifugal process babbitts the white metal.
Technicians perform final machining strictly according to the stipulated specifications and tolerances.
Experienced quality control engineers conduct the final inspection before dispatch.

REVERSE ENGINEERING, DEVELOPMENT, AND BEARING MANUFACTURER

We are experts in the development and bearing manufacturer, either from the sample or from the drawing provided to us by the client.
Our housing facility prepares drawings of old bearings using the latest CAD-CAM version and develops them to manufacture new bearings.
Our experienced technicians take the dimensions of old bearings and incorporate them while preparing development drawings.
We use all the instruments that are calibrated for taking measurements of old bearings.

THE ADVANTAGE OF THE DEVELOPMENT OF A NEW WHITE METAL BABBITT BEARING FROM THE SAMPLE OF OLD BEARING:-

It is generally known that as the heavy engineering plants get old, they need to replace the bearings. It is rather impossible to arrange new bearings from the manufacturer of the main equipment as they have either closed their unit or discontinued the particular model of the equipment.
We have assisted hundreds of clients based all over the world by developing and manufacturing new White metal bearings according to the sample or the drawing furnished by them.
We can also depute our service engineer equipped with instruments and cad-cam software to prepare the manufacturing drawing onsite, in case it is not possible to remove the bearing and transport it to our works.

GUARANTEED PERFORMANCE AND LONG LIFE OF BABBITT WHITE METAL:-

We guarantee satisfactory performance for all bearings we develop and manufacture.

Delivery in a short time is possible.

We are well-known for our competitive prices and international standard of quality.

We regularly export bearings to countries across Asia and the Middle East, including Bahrain, Bangladesh, Japan, Malaysia, and many others.

Babbitt Bearing | White Metal Babbitt Bearing | Bearing Manufacturer

Raj — Thu, 08 Oct 2020 07:50:24 +0000

RA Power Solutions manufactures new white metal babbitt bearings as per the drawing or sample. We also undertake repair and rebabbitting of old white metal babbitt bearings, which get worn out or damaged due to an accident.

Rebabbitting Bearings with Centrifugal Casting

The rebabbitting of old bearings and babbitting of new bearings by the centrifugal casting process is the most popular. It results in high-quality bonding between the babbitt white metal and steel lining of the bearing. In this process, we spin babbitt metal to the bearing housing (outer steel lining of the bearing) in spin fixtures. Variable-speed drive units actuate the process and ensure proper alloying and bonding of white metal with the steel shell. We strictly control the temperature of the white metal and the bearing shell.

Static Pouring Process:

We commonly use the process of static pouring of babbitt white metal. We follow this method when the centrifugal process is not possible due to design restrictions or the profile of the white metal bearing.

Pour each bearing with a continuous pour of white metal, eliminating the possibility of cracks or joints in the babbitt. This also avoids any possibility of premature failure of bearings.

Inspection of Bearings After Rebabbitting

Rough Machining and Final Machining of Bearings

We have an in-house facility for rough machining and final machining of bearings after babbitting the white metal. We machine the inner diameter and other critical dimensions on CNC machines fitted with DRDO devices.

This ensures that the white metal babbitt bearing, after manufacturing or rebabbitting, has all dimensions exactly as per the drawing and specified tolerances. As a repair company, we understand the importance of maintaining critical dimensions.

We are an ISO 9001:2015 certified company and follow strict quality control, which includes the following:

MPI for crack detection of bearing shell before white metal babbitting process. A Level II qualified technician performs this work. The technician conducts the MPI test for crack detection before and after the shot blasting process.
We do not accept any cracks in the bearing steel shell. If we observe a crack, we either reject the bearing shell or, in consultation with our senior engineers, remove the cracked area by the scooping process. We check the bonding of white metal with the steel shell by ultrasound. We do not accept any abnormality.
We thoroughly check dimensional accuracy for taper, ovality, and all other critical dimensions important for assembly.
24×7 repair services for rebabbitting.

We understand the urgency of white metal babbitt bearings, especially when clients send them to us for repair.
