Mechanical dismount of bearings is carried out with an extractor. Extraction is required on the tight ring.

The choice of extractor depends on:

  • the diameter: to define the scope, spacing and the force required for extraction
  • the accessibility: external, internal, or special
  • the method of extraction: choice of fulcrum ; from the center line of the shaft or the exterior or using extraction accessories. Extractors equipped with pump and hydraulic cylinder offer your operators a larger extraction force compared to manual method. Setup is simplified due to the self-centring system of the arms.

NTN-SNR advises you according to your needs and offers a full range of extractors that are simple to use, robust and safe.

Opt for hydraulic dismounting, for any size bearing, requiring high extraction forces.

2 methods of bearing extraction are available to you:

  • extraction from tapered bearing seats
  • extraction with adaptor or withdrawl sleeve by hydraulic nut

Discover our range of hydraulic nuts for dismounting your bearings.
