Bearing designs

The research establishment ZKL - Vyzkum a vyvoj, a. s. is primarily engaged in analysis of the inner geometry of rolling bearings, analysis of contact stresses in a particular contact area of bearing parts and in solution of tribological questions.

Its workstation has at disposal a modern computer technology with its own software programs based on decades lasting experiences, enabling to maximally optimize the designs, taking into account the required operating conditions, service life and reliability of bearings. The facility improves the utility values of all types of rolling bearings, namely their basic load ratings, durability, limiting speed frequencies, operating temperature limits, friction load and vibration level reductions.

It expands the principal assortment of standard bearings by introduction of new, advanced materials.

It develops special-purpose bearings for highly demanding operation conditions or in non-standard types of mountings.

It also widens the basic manufacturing assortment of bearings by introduction of new design series for broad range of use in the engineering industry and in other fields.

The establishment develops the rolling bearings for use in:

  • automotive industry
  • transport and lifting mechanisms
  • vibration machinery
  • railways
  • robots and handling equipment
  • electric motors
  • aviation industry
  • power engineering inclusive of nuclear power plants
  • machine tools
  • chipless forming machines
  • mining and metallurgical industries
  • agricultural machinery
  • wood-working industry
  • stone processing industry
  • many other fields
