Bearing Testing Methods and Strategies

The main reasons for bearing testing are:
• Technical validation / supplier approval
• Comparative assessment (applies to different suppliers or to different production methods)
• Continuous quality control for incoming or outgoing inspections
We use an overview of different testing methods, the required equipment and testing strategies. The main testing methods are for frictional torque or temperature and for endurance. Both have their merits, depending on what is critical in the application in question.
