We produce various types of slip rings, which we divide to the following groups:

  • Standard slip rings
  • Slip ring for EV
  • Special slip rings

The innovative technical solutions, developed by Kolektor in the domain of the construction of the slip ring, contributed to the elimination of the possibility of the appearance of hidden defects on the product itself.
And speaking of the competitive advantage, it is presented also by the advanced and completely automated production process, which can be adapted, extensively, to the requirements of the individual client and market. The client can recognize the combined effect at his production line in the reduced reject of semi-products (rotors).
