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.

Special Size Engine Bearings | Undersize Marine Engine Bearings

Raj — Thu, 16 May 2019 08:33:53 +0000

RA Power Solutions undertakes on site repair of the crankshafts of main and auxiliary engines installed on vessels, as well as high-capacity engines used for various applications. The crankshaft repair is undertaken by the use of specially designed portable, compact, and lightweight onsite crankshaft grinding machines, which are designed, developed, and manufactured.

After grinding the crankpin and main journal of the crankshaft, undersized bearings are required. Manufacturers and their agents often do not have these undersized bearings readily available. RA Power Solutions maintains a large stock of undersized bearings for crankpins and main journals. We supply bearings for main and auxiliary engines of all popular makes and models installed on vessels.

The bearings are imported from Japan and Europe. The ready availability of bearings reduces the downtime of the engine. RA Power Solutions supplies main journal and crankpin bearings with a guarantee of satisfactory performance for 2,500 hours of operation or 12 months from the date of dispatch.

Wartsila , Daihatsu , MWM , Caterpillar , MaN , MaK , B&W , Sulzer , Bergen , Detroit Diesel , Stork Werkspoor , Pielstick , Deutz , Yanmar , MTU , Cummins , Nohab Polar , Caterpillar , Mitsubishi , Yanmar , MaK 551 , MaK 552 , MaK 453 , MaK 451 AK , MaK 452 AK , Deutz 540 , Deutz 358 , Deutz 350, Pielstick PC 2.2 PC 2.5, Wartsila 524 ,Wartsila 824 TS, Sulzer 6 AL 25/30, Sulzer 5 AL 25/30 MWM TBD 484, MaN 40/54 , MaN Sulzer 12 ASV 25/30 , Sulzer 16 ZV 40/48 , Deutz BV 16M 540 , B&W 6L 45 GFCA, MAN B&W 55/GF, CAT D353, B&W 5T23LH, Daihatsu 6 PST 26D, Daihatsu 6 PSHTb 26M, Mak 6MU 451 AK, Deutz 6M 628, Caterpillar 3512, Deutz BV 12M 628, MWM TBD 234, WICHMANN 5AX, SKL 8NVD 48A-2U, Pielstick PC 2.2 LNR, Caterpillar 3508 and more.

We have been repairing crankshafts for over forty-five years. In some cases, we encounter crankpins or main journals that require reducing the diameter beyond the manufacturer’s last specified limits. In this situation, the user has no option but to reject the crankshaft and purchase the new crankshaft, the cost of which is exorbitant, and the procurement period is long.
