On-Site Crankshaft Grinding Machine | Crankshaft Polishing Machine – RA Power Solutions

Crankshaft grinding machines are designed to maintain the accurate tolerances as per the engine manufacturer’s recommendation

Generally, it is observed that even for the higher diameter of crankpin and main journal of the crankshaft the tolerances do not exceed more than 0.05mm in order to achieve such close tolerances of crankpin and main journal of crankshaft RA power designs and manufactures on-site crankshaft grinding machine which has the capability to maintain the close tolerance of even 0.01mm/0.02mm which is far better than the close tolerance specified by the engine manufacturers.

The on-site crankshaft grinding machine and crankshaft polishing machine manufactured by RA power solutions has the following features:

    1. Crankshaft grinding machine is designed in a way that it can be inserted from the inspection window of the engine block thus there is no need of removal of the crankshaft from the engine block.

    2. In case of space restrictions, RA power has the capability to design the equipment according to the space available on site for grinding or polishing of crankshaft/turbine/alternator shaft/rotor shaft etc…

    3. The on-site crankshaft grinding machine is lightweight portable and can be easily carried to the site all over the world. The crankshaft grinding  machine is packed in the suitcase and is carried as accompanied baggage accepted by all international airlines

    4. The main body of crankshaft grinding equipment is manufactured out of titanium alloy which is lightweight and can absorb the vibrations this feature of crankshaft grinding machine facilitates RA power technicians to undertake crankshaft repair on board the vessel while it is sailing, maintaining the close tolerances within 20 microns.

    5. Crankshaft grinding machine designed and manufactured by RA power can presently work up to 700mm diameter which we are in process of extending up to 1000mm.


RA power has sold more than 70 crankshafts grinding machines all over the world which are performing satisfactorily the cost of the machine is low and is affordable for repair workshop, shipping company, power plants etc…

White Metal Babbitt Bearing – RA Power Solutions

White metal Babbitt Bearing            White-metal-Bearings-300x198

White metal Babbitt bearing is used in engines, turbines, alternator, pumps and various other Rotating equipments. It is important that the grade and quality of white metal which is used for babbitting of bearing is selected based on the load characteristics, operational condition on the Babbitt bearing.

The white metal babbitting is done by centrifugal system and this ensures that the Babbitt white metal bonds properly with the steel base of the bearing. The quality of Babbitt bearing is checked by ultrasound for bonding.

RA Power Solutions Pvt. Ltd. undertakes babbitting of white metal bearing up to 1500 mm inner diameter. The babbitting is done by the experienced technicians and is done by centrifugal process which ensures that Babbitt white metal forms a uniform layer. The grade and quality of white metal used for babbitting is carefully selected.

The in-house machining facility ensures that all the parameters of bearings are maintained as per the manufacturer’s specifications and tolerances.
