E-mail: elektromotory@sammetal.cz

Our company carries out repairs of mechanical parts of electric motors and generators:

  • renovation of shafts (single pins, bearing surfaces for sliding or rolling bearings, stuffing diameters, rotor packing)
  • bearing shields (bearing holes for mounting the bearings, stator mounting)
  • bearing caps and sprayers
  • bearing houses
  • cases

At the same time, we apply protection against bearing currents by apllying an insulating coatings on the surface of the bearing surfaces of the shafts or bearing holes in the bearing shields.
