Demanding requirements call for extreme tribometers

Cost, safety and reliability aspects are of paramount importance in the aerospace industry.

Every single component has a significant influence on the entire system's reliability and longevity. Likewise, however, each component is subject to demanding requirements, including different load and ambient conditions, changing atmospheric conditions, corrosive gases, high pressure or vacuum, extreme temperature fluctuations and different forces. The requirements profile for tribological measurements resulting therefrom requires the test setup to be as close to practice as possible. Optimol tribometers are perfectly capable of simulating these conditions. Materials, coatings and components can be analysed and optimised on the basis of customised tests. Unique on the market, the possibilities, special designs and options available for our tribometers and test benches leave nothing to be desired. We prove our competency time and again by offering solutions for extreme requirements.
