White Metal Bearing By RA Power Solutions

 

White Metal Babbitt Bearing Repair:

There may be numerous reasons for the failure of white metal bearing. Few of them are listed below:

• Poor quality of lubricating oil used.
• Presence of foreign particles.
• Poor filtration system.
• Inappropriate grade of white metal used for babbitting of bearing at the time of manufacturing or repair.
• Poor bonding between  the babbitt white metal and steel lining.
• Development of excessive taper and ovality on the shaft which is resting on the white metal babbitt bearing.
• Development of rough surface, line marks and pitting on the shaft.

Manufacturing & Repair of White Metal Babbitt Bearings Undertaken by RA Power Solutions:

A leading organization having experience exceeding 40 years in the field of repair, maintenance and overhaul of high capacity diesel engine and mechanical equipments installed on vessel, power plants and heavy engineering companies. The rebabbitting of old bearings and manufacturing of new bearings up to the diameter of 1500 mm is undertaken by RA Power Solutions.

Manufacturing of new white metal babbitt bearing and repair of old damaged/worn out white metal babbitt bearing is undertaken strictly by centrifugal system of casting babbitt to the base metal. Thus the centrifugal process of rebabbitting ensures proper bonding between the white metal and the steel casing, dense and white metal babbitting without any pinholes and flaws.

Manufacturing of Bearing is in Process	Bearings After Rebabbitting

Generally following procedure is adopted in order to maximize the lifetime of old bearing or new bearing manufactured by RA Power Solutions:

• Incase of old bearing, the white metal babbitt is removed under a strict supervision of experienced technicians.
• The melting pot temperature is strictly controled for easy removal of white metal from the steel casing.
• Bearing shell is subject to hardness test.
• The white metal bonding on the hardened surface results to the failure. Hence the hard spots are removed by the scooping procedure.
• Bearing shell is subject to crack detection by MPI. No cracks whatsoever are accepted.
• The bearing shell is sand blasted.
• All the dimensions including the profile of the bearing is checked and recorded.
• In case of thin shell type of bearing having thickness of 4mm to 9 mm dedicated die and tooling is designed and fabricated to maintain the original profile and crush height.
•  Rebabbitting of babbitt white metal is done using high quality centrifugal casting equipment
  with full control of temperature.
• Final machining is undertaken on latest CNC equipment maintaining the dimensions strictly as per the manufacturer's specifications.
• Final quality checks like ultrasound, MPI, dimensional inspection is undertaken by experienced technicians and reports are shared.

Our Recommendation: It is our experience that while old bearings are repaired maintaining the high quality and dimensions as per the manufacturer requirement but no attention is paid on the shaft which is supported on the white metal babbitt bearing.

Generally following defects are observed on the shaft which may cause the failure of white metal bearing:

• Development of excessive taper and ovality in the shaft. This needs to be checked by the experienced technician prior to the fitment of white metal babbitt bearing.
• Presence of bearing line marks and pitting. This needs to be removed prior to the fitment of white metal babbitt bearing
• No importance is given to the surface finish of the shaft on which bearing is placed. This is important for long life of bearing and shaft. The recommended shaft surface finish is 0.20 RA value.
• Loss of alignment of the shaft. This needs to be checked.
• Improper oil gap between the bearing and the shaft.

RA Power Solutions has onsite grinding and polishing machine which can be taken to the site and fine polishing to improve the surface finish can be undertaken without disassembly of the equipment. We have the machines available up to 700mm in terms of diameter which can be carried to the site anywhere in the world.

The only company in the world which offers comprehensive services under one roof with guarantee which includes rebabbitting of bearings, inspection and repair of shaft and load trail.
