Rotor Shaft Grinding

In  industry and power generation plant turbines are running continuously. The rotor shaft which is supported on white metal Babbitt bearing gets worn out developing taper, ovality, bearing line marks and damage to the white metal Babbitt bearing.

RAP undertakes on site repair of rotor shaft bearing sitting diameter. There is no requirement of disassembly of rotor shaft. The rotor shaft diameter is dimensionally checked by experienced engineers. The hardness and crack detection test is also undertaken which is of great importance. The grinding of rotor shaft diameter is undertaken by portable rotor shaft grinding machine. The tolerance within 20 microns is achieved with a requisite surface finish. We have facilities to undertake rotor shaft grinding and polishing up to 700 mm diameter. We work in two shifts of 12 hours each to reduce the downtime.

We also design and manufacture rotor shaft grinding machine as per site requirement up to 700 mm and have sold more then  60 machines all over the world.

RA Power Solutions recently successfully repaired 160 MW rotor shaft of a turbine installed in a leading cement plant in North India. The plant owners have a major challenge of keeping aging turbines up and running efficiently and cost effectively. Matching white metal Babbitt bearings having bore size of 430 mm were also supplied.
