FARAX®-SSP180

CEC-Compliant Synchronizer Test Bench

The FARAX®-SSP180 is a high-precision test bench for the evaluation of synchronizer ring performance, based on the well-established FZG methodology developed at the Technical University of Munich. It provides deep insights into the friction and wear behavior of synchronizer systems, using standardized and proven test cycles under realistic conditions.
