RA Power Solutions maintains main and auxiliary engine bearings for leading engine manufacturers and their various models.

With over 46 years of global experience in crankshaft repair, we understand the challenges shipowners and power plant operators face during engine overhauls. In many cases, undersized bearings for crankpins and main journals are not readily available in the market. As a result, engine commissioning is often delayed after the repair process.

Moreover, sourcing customized or non-standard bearing sizes can take considerable time. Project schedules are prolonged, operating expenses rise, and vessel downtime becomes inevitable as a result. Therefore, choosing a repair partner that can provide immediate technical solutions and alternative bearing support is critical for minimizing delays and ensuring smooth engine performance.

Development of Special-Size Crankpin and Main Journal Bearings

R A Power Solutions also maintains a stock of crankpin and main journal bearings that are undersized beyond the manufacturer’s recommendations. The ready availability of special-size bearings has saved many crankshafts from rejection.

Main Journal Bearings

Engine Bearing Manufacturers

Crankpin Bearing Suppliers

Special-size crankpin and main journal bearings are critical to making sure an engine runs well after a crankshaft repair. When typical undersized bearings aren’t available, custom-engineered solutions are necessary to avoid expensive downtime and delays in commissioning. So, precision manufacture, precise dimensional control, and high-quality Babbitt lining are all done very carefully to meet the exact specifications for the crankpin and main journal.

Also, innovative manufacturing methods and thorough quality checks make sure that the load is evenly distributed, friction is low, and the life of the bearings is longer. Because of this, special-size journal bearings are a reliable choice for marine engines, power plants, and heavy industrial uses.

FAQs

1. What are crankpin and main journal bearings used for in an engine?

Crankpin bearings support the crankpins, while main journal bearings support the crankshaft main journals; both reduce friction between moving parts and ensure smooth engine rotation, especially after grinding or repair work.

2. Why are undersized bearings sometimes required after crankshaft repair?

When crankpins or main journals are ground to remove wear or damage, their diameters are reduced. As a result, undersized bearings are needed to maintain correct clearances and proper lubrication.

3. Does RA Power Solutions stock both standard- and special-sized bearings?

Yes—the company maintains a large inventory of standard, undersized, and special-size crankpin and main journal bearings for many popular engine makes and models, helping minimize downtime.

4. Which engine brands are supported with ready-to-use or custom bearings?

RA Power Solutions supports top manufacturers such as Wartsila, Daihatsu, MAN, Sulzer, Yanmar, MWM, Caterpillar, MTU, Cummins, and more, with a wide range of bearing sizes in stock.

5. Can special-size bearings extend the life of a repaired crankshaft?

Absolutely — custom bearings made beyond OEM undersize limits can save crankshafts that would otherwise be rejected, ensuring reliable performance and reducing the need for costly replacements.

white metal bearings

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.

FAQs

1. What are the typical compositions of tin‑ and lead‑based Babbitt alloys?

Tin-based Babbitts generally contain 80–90% tin, 5–15% antimony, and 1–6% copper, while lead-based ones include 70–80% lead, 5–15% antimony, and minor copper or tin .

2. How do tin-based and lead-based Babbitts compare in performance?

Tin-based alloys offer higher load capacity and speed resistance, plus they tolerate higher temperatures—ideal for demanding applications. Lead-based alloys are softer, more corrosion-resistant, and more cost-effective for moderate loads .

3. Which alloy type suits marine and turbine bearings?

RA Power Solutions supplies both tin- and lead-based Babbitt alloys tailored to client specs. Tin-based versions are preferred for turbines and high-speed machinery, while lead-based are ideal for marine and high-humidity environments .

Babbitt Bearing – RA Power Solutions

Babbitt bearings have vast applications in power plants, heavy machinery, diesel engines, and more. The selection of Babbitt white metal must be based on the bearing’s application, shaft RPM, load, and various design aspects.

Alternator Bearing of Wartsila Diesel Engine

RA Power Solutions Pvt. Ltd. manufactures white metal Babbitt bearings with diameters up to 1500 mm. We select the outer steel casing material based on the application, and our design parameters determine the grade of white metal. We import Babbitt white metal from a leading manufacturing company in Spain. Our team applies the white metal to the steel casing using a centrifugal babbitting system to achieve a strong bond. This proven method is widely used across the industry. We maintain the white metal thickness strictly according to the specified requirements.

We have in-house facilities to perform various machining operations after white metal babbitting. The bore size is maintained within the tolerances specified by the manufacturer.

Journal Bearing of Marine Engine

Our Technicians also rebabbit old bearings. Our team removes the old Babbitt white metal and inspects the steel casing for cracks, excessive hardness, and profile deformation. If the steel casing meets all required parameters, we rebabbit the bearing using the same grade or a superior grade of Babbitt white metal. This process ensures significantly better performance after rebabbitting.

We export new Babbitt bearings and also offer rebabbitting services for old bearings to reputed companies worldwide. We prioritise quality and offer competitive pricing with a minimal delivery period.

FAQs:

1. What is a Babbitt bearing?

A: A Babbitt bearing features a white metal lining that supports rotating shafts and reduces friction in machinery.

2. How are Babbitt bearings manufactured?

A: Manufacturers cast the white metal alloy onto a steel backing and machine it to exact specifications.

3. What is rebabbitting?

A: Rebabbitting is replacing worn Babbitt metal inside a bearing shell to restore its original performance.

4. Where are Babbitt bearings used?

A: Industries use them in turbines, engines, compressors, and other industrial equipment that require smooth rotational motion.

5. Why rebabbit bearings instead of rebabbitting them?

A: Rebabbitting restores bearings at a lower cost, extends service life, and reduces downtime.
