In Situ Crankshaft Grinding

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 supplies undersized bearings and crankpin bearings for marine and power plant engines for YANMAR, MAN, DAIHATSU, and MAK. We also have standard bearings for various engine models. If the crankshaft journal is ground smaller than the standard size, undersized bearings are required. The bearing must match the crankshaft's final diameter to maintain proper clearance and ensure the engine runs smoothly. We also provide YANMAR 6N18AL-DN/DV bearings for engines with a normal journal diameter of about 145 mm. Bearing selection is done after grinding the crankshaft diameter. Then the correct main bearing or crankpin bearing is chosen according to the final size and necessary clearance. Availability of the bearing depends on the engine model and the size of the bearing needed. Comprehensive Stock of Undersize Bearings We maintain an extensive inventory of undersize bearings for the following engine models: Undersized bearings of Yanmar diesel engine model 6N18AL-DN/DV ha...
