It is observed that in power plants and heavy industries, the turbine shafts, alternator shafts, rotor shafts, pumps, and crankshafts operate continuously without any break. The babbitt white metal bearings, which support the shafts, get worn out due to continuous operation or get damaged due to an accident.

We have observed that while the white metal bearings are promptly replaced, no action is taken on the shaft, which is supported by the bearings.

RA Power Solutions has introduced a revolutionary onsite polishing machine, details of which are given below:-

• Enhance the life of the turbine shafts, alternator shafts, rotor shafts, pumps, and crankshafts by onsite polishing.
• As mentioned above, the damaged or worn-out bearings are replaced, but no attention is given to the shaft. We offer comprehensive services and an annual contract for the polishing of the shafts installed in your factory.

The details of polishing are as follows:-

• We depute a team of technicians who are experienced to undertake dimensional inspection of the shaft to check the taper and ovality. The inspection is done by the calibrated instruments.
• The hardness of the shaft and crack detection by MPI are undertaken. This is required only in case of accidents.
• The surface finish of the bearing sitting area of the shaft is checked. We use an advanced Mitutoyo surface finish instrument to check.
• Visual inspection is undertaken to check the pitting, bearing line marks, etc.

Use of onsite polishing equipment

We have portable onsite polishing equipment, which is carried by technicians to any site all over the world. This revolutionary onsite polishing equipment is capable of removing high points, bearing line marks, and pitting. The stock removal can be as low as 0.01 mm, thus there is no change in the oil gap and the dimension of the shaft.

Increase the life of turbine shafts, alternator shafts, rotor shafts, pumps, and crankshafts

Our clients all over the world have experienced that polishing the shafts before fitment of white metal babbitt bearing increases not only the life of bearings but also of the shaft. It avoids a major breakdown of the shaft, bearing, and the plant.

NO REQUIREMENT OF REMOVAL OF THE SHAFT FROM THE MAIN EQUIPMENT

At RA Power Solutions, it is possible to undertake the polishing of the shaft without any disassembly, hence, minimum downtime and high surface finish can be achieved onsite.

LOW COST OF POLISHING

The cost of onsite polishing is marginal. It prevents long-term damage to the bearing and shaft. The technology is now easily available. Power plants, industries, and shipping companies can benefit from it. It is ideal for all rotary equipment.
