Intermediate Shaft Repair and Rebabbitting of Intermediate Shaft Bearing

About Intermediate Shaft Repair and Rebabbitting of Intermediate Shaft Bearing

RA Power Solutions was approached by a leading shipping company based in Vietnam. The vessel was approaching Kochi Port India, and serious damage was reported to the intermediate shaft and bearing.

RA Power Solutions three technicians boarded the vessel and their main observations are as following:-

Intermediate Shaft

• On removal of Intermediate Shaft bearing the excessive damage to the bearing seating area was observed.
• The Intermediate Shaft bearing, babbitt white metal was badly stuck on the bearing journal diameter.
• After removal of white metal from the Intermediate Shaft bearing seating area the ovality of 0.38 MM was observed, and the standard diameter of Intermediate Shaft Journal is 505.00 MM.
• Hardness and MPI Tests were undertaken and observed within limits.
• Localized damage, Bearing line marks, and Rough surface were observed on Intermediate Shaft Journal diameter.
• Intermediate Shaft Journal diameter was repaired by in situ grinding and polishing machine and diameter was maintained as 504.00 MM. The intermediate shaft bearing seating diameter was reduced by 1.0 mm.

Repair of Intermediate Shaft Bearing

• After removal of damaged babbitt white metal Intermediate Shaft bearing from the vessel, it was transported to our works based in IMT Manesar near New Delhi by Air, A distance of more than 2600 KM from Kochi Port India.
• The inspection of damaged bearing was undertaken, the bearing was rebabbitted and machining was done maintaining the inner diameter of 504.50 MM, as per the oil gap mentioned in the manual.
• Bearing was again returned to the Kochi Port India and was hand-carried by our representative to save time.

Assembly of Intermediate Bearing and Shaft

• The bearing was Assembled by RA Power Solutions Technicians.
• All the parameters including Oil-gap and Blue Matching of the bearing was done with Intermediate Shaft.
• After assembly trials were taken, the performance of the Intermediate Shaft and bearing was observed satisfactory. The job was executed in a short duration of Eight (8) days.

Precision Shaft Repair for Maximum Reliability

Our shaft repair process restores intermediate shaft assemblies to peak operational standards. Precision machining, polishing, and component alignment guarantee a smooth operation and high radial load capacity, essential for heavy machinery usage. We perform repairs using quality materials and advanced procedures to maximize durability.


Rebabbitting for Extended Service Life

The rebabbitting of bearings incorporates high-grade white metal, poured under controlled temperatures to establish consistent purity and strength. Each bearing undergoes ultrasonic and dye penetrant testing, assuring integrity and safety. This process considerably improves wear resistance and bearing longevity in demanding environments.


Custom Fitment and Inspection Services

We offer tailored fitment for a variety of bore and outside diameters, accommodating client specifications. Our team ensures every assembly meets ISO precision ratings. Rigorous inspection routines, including non-destructive testing, reinforce reliability and minimize future downtime for maintenance.
