A technology of creating of geographically distributed multi-operator control of mechatronic devices via the Internet is This research work deals with some numerical investigations on the static stiffness of machine tools ball bearing linear guides. Finite Elements Method (FEM) is employed to carry out the simulations using ANSYS software. Previously, we have conducted some experimental researches of the guide's stiffness in different directions such as radial, lateral and angular directions. As experimental researches cost a lot of time and money, it is necessary to use numerical methods at the design stage and also for further investigations. Therefore, more data are available and the experiments can be concentrated to the most important fields. In this work a FEM model of the guides is developed and the results are compared to the experimental ones. A good agreement has been found to be between the experimental and numerical results.
