Model 2500 Rotary Fatigue Machine


The Model 2500 is designed to determine the integrity of wheel and brake components by replicating the force on the components by controlling the magnitude of the cornering forces consistently. This machine tests rotors, wheels, bearing packs, axle extenders, etc., by mounting the test components vertically on a rotating table and applying a varying load at an adjustable angle.

The control system maintains a constant force on the load arm while spinning the rotary table at the desired test speed. The test is complete when either the test part fails, or the required number of rotations is reached.
