2disk - Two-Disk Test Bench

Our Two-Disc test bench is the number one choice when it comes to testing materials, coatings or lubricants in heavily stressed, lubricated rolling contacts. A tried and tested tribological model test bench, it is used for basic tribological testing using two discs which are individually driven and compressed in a defined manner. It can be used to study tribological systems subjected to stress generated by rolling and sliding motions. Function and application-oriented practical simulations as they occur in rolling bearings, gears, cam followers and wheel-rail systems.

Two cylindrical discs are mounted on separately rotating drive shafts. These are pressed against each other at their lateral surfaces. The load, temperature, speed and slip variables can be varied dynamically. In addition to these variables, the friction force and the total linear wear can be measured continuously during the process. Both drives can be parameterised synchronously (master-slave operation with adjustable slip) or asynchronously (independent speed control of both drives).
