Our services are based on many years of experience from implemented projects and our own know-how. However, in addition to bearing development, bearing seating and the application of contact mechanics know-how to the development of gears, cams, motion screws and linear guides, the portfolio also includes other activities: design of mechanical components or simpler sheet metal forming press tool dies. All design work takes place in the Creo Parametric software.

Simulation and calculation software, including Marc, Patran, Apex and Adams, allows you to solve both static and dynamic linear and non-linear issues. In addition to commercial software, we have internally developed other tools that speed up and improve our work - such as software for calculating the properties of the lubricating film.
