Noise and vibration testing for bearings


A noisy application might be caused by wavy bearing components, local defects in the rings and balls or by dirt particles in the bearing. While basic requirements for a bearing such as stiffness, load capacity, speed limit and service life play a critical role in applications, low noise and vibration are even more important. All of these quality issues for bearings can be tested with the following bearing vibration equipment: SN-X, S9912-X. High-tech analyses and measurements such as frequency analysis and further advanced analyses pinpoint faults. Spectral masks help to optimize the bearing performance in the particular customer application. With some experience, the measurement results of these machines can also be used by experts to detect imperfect manufacturing steps. The introduction of a worldwide calibration system enables vibration equipment to operate according to international standards.
