Mobility

Keeping track of friction and wear with tribometers for all kinds of applications

Quick and cost-effective development processes, precise specifications and sustainable solution concepts thanks to application-oriented tribometry

Hardly any other industrial sector is targeted as much by politics and the public as the mobility sector. Sustainable and durable means of transport with energy-efficient drive systems have to be brought onto the market in ever decreasing innovation cycles as well as in a cost-effective manner. This is where our application-oriented, versatile and highly precise tribological solution concepts come into play. Taking into account the aspects of wear resistance and energy efficiency, we help our customers and partners specify materials and operating fluids as early as during the design and predevelopment stage. When doing so, we always start with a holistic system analysis and the definition of the demands placed on the component to be specified. Based on that, we cooperate with our customers and partners to develop test methods that are able to differentiate and specify the friction, wear and fatigue behaviour of materials and operating fluids, surface finishes, heat treatments and entire components in a precise, robust and time-saving manner. Take a look at the categories listed below and discover the test methods and solution concepts that we hold ready for you.
