Growing requirements for performance, emissions, consumption and service life of modern engines are the great challenges facing engine manufacturers today. Investment in research and development has grown considerably. With highly flexible CENTAX-TEST, CENTA provides a suitable test bed coupling for such tasks. Due to its torsionally soft characteristics, vibrations in the drive train are reduced, while the couplings compensate axial, radial and angular misalignments. This conserves both the test bed and test sample, thereby prolonging operating lives. Moreover, all values established under such conditions provide a much more accurate picture. Whether in combination with a gasoline or a diesel engine, whether for new designs or for monitoring serial production: the couplings provide the optimum conditions for test purposes.
