Technical calculation


From theory into practice

As a company that is geared to the future, we invest in the development of your products. We use modern simulation processes, test stands, and laboratories for physical and chemical tests.


Customer-specific bearing systems and components are standard for the INA and FAG brands. The use of state-of-the-art tools such as CAD goes without saying and is beneficial for both parties.

Calculation and selection

By using BEARINX® software developed by the Schaeffler Group, we are able to model and calculate complex shaft systems as well as entire transmissions. The internal loads of all bearing types right down to individual rolling element contact are calculated and can be displayed as a table or a graph. From the loads of each contact, BEARINX® accurately determines the calculated operating life of the bearing system.


In the design and modeling phase, state-of-the-art methods such as dynamic simulation and FEA analysis are used. By means of "rapid prototyping", the customer can even order a dimensionally-accurate model that can be tested for fit and form in the application.

The task of the technical calculation is to check the function and operational strength of individual components, and of the overall system. To resolve these complex issues, suitable models are constructed and calculated using appropriate software packages, in the following areas:

  • Kinematics and kinetics
  • Finite-element method
  • Topology optimization
  • Operational strength
  • Residual stress analyses
  • Multi-body dynamic simulation
  • Hydraulics (1D, CFD)
  • Charge cycle simulation
  • Mechatronics
  • Tribologiy
