Safety of the machines and evaluation of backup systems is fundamental for the industry to develop a secure environment for the employee and ensure that components do not get damaged in case of a failure. Having the possibility to test the behavior of a bearing under the extreme stress of a simulated failure scenario is an important capability that allows to practically test these complex components. The test bench aims to characterize the behavior of the shaft when drop down at high speed on a backup bearing set. The machine was developed and designed to have a high rpm speed of test and quick maintenance and calibration.
