In Situ Crankshaft Grinding

Wartsila diesel generating sets, popular models being 12V32, 18V32, and L20, are extensively used in diesel power plants and on board vessels. Wartsila alternator bearings need to be replaced after a long term of work or accidental damage due to continuous work and heavy working conditions. RA Power Solutions has over 46 years of experience in manufacturing and supplying new Wartsila Generator/Alternator Bearings up to 600 mm diameter. Bearings can be made to suit the correct fit and application, according to the required drawing, sample, part number, or dimensions.  Alternator Bearing Surface Before Rebabbitting Service The common causes of damage to Wartsila alternator bearings are as follows: i) Wear and tear of alternator bearings due to continuous operation ii) Development of taper and ovality in the bearing iii) Low lubricating oil pressure, pump failure, or blocked oil passages iv) Misalignment of the shaft  v) Disturbance in the bedplate foundation Action Taken by RA...

Wärtsilä alternator and generator bearings are exposed to continuous operating conditions and stresses from load, vibration, heat, and lubrication. The Babbitt white metal lining can wear, score, crack, fatigue, or become damaged over time. When the original shell is suitable for repair, rebabbitting of Wärtsilä alternator bearings is an effective way of restoring the bearing. RA Power Solutions has over 47 years of experience in Babbitt white metal bearing repair and rebabbitting. Careful inspection, controlled bonding, precision machining, and final dimensional checks are performed to restore the bearing for reliable service. Wartsila Alternator Bearing Repair Procedure Before rebabbitting, the bearing is examined carefully to determine the condition of the shell and the existing white metal lining. The damaged Babbitt is all taken out, and the shell is cleaned and fitted for the new lining. Damaged Wärtsilä Alternator (Generator) Bearing Before Rebabbitting Wärtsilä Alternator (Ge...

RA Power Solutions offers tri-metal engine bearings for the crankpin and main journal of crankshafts for marine and industrial engines. We offer main and auxiliary engine crankshaft grinding, repair , and maintenance services on board vessels. Our services are also available for high-capacity engines in power plants worldwide. Engine manufacturers generally carry standard-size bearings. However, it is often difficult to get the necessary small tri-metal bearings for crankpins and main journals after grinding the crankshaft. To meet this need, we offer a wide range of undersized bearings for various engine makes and models.  Undersized crankpin bearings   Undersized crankpin bearings Crankpin Bearings For MAN & MAK Engines White metal babbitt bearings Undersized Bearings of Yanmar Diesel Engine Requirement of Undersized Tri-Metal Bearings for Crankshaft After grinding of the crankpin and main journal of the crankshaft, there is a requirement for undersized bearings, whic...
