Wheel bearings on passenger and commercial cars are one component to important. A False brinell phenomenon observed on the wheel bearing of the vehicle represents the dent generated on a raceway due to balls and the corrosion during transportation on train. To verify the False brinell performance during the development process of wheel bearings most of a False brinell test is performed on test rigs prior to the vehicle test due to cost and time. But the different False brinell results are affected by diversities such as a structural concept, a loading system, and characteristics of test rigs itself. This paper shows the development of the instrumented device that can measure a strain on a wheel bearing and analyze a relation between a False brinell of the wheel bearing and a measured strain under the different loading condition on two test rigs. To verify the reliability of this study, a depth of the brinell is measured and compared. A bench test and a vehicle simulated test were carried out. The initial results of the test show the different False brinell performances and strains under test setups, but after the adjustment loading condition the results have a equivalent severity.
