In addition to the basic requirements on a bearing like stiffness, load capacity, speed limit and life time; low noise and vibration is becoming more and more important in most applications. Beside others, a noisy application might be caused by wavy bearing components, by local defects in the rings and balls, or by dirt particles in the bearing. All of these bearing quality issues can be tested with QTC´s bearing vibration equipment.
High tech analysis and measurement such as frequency analysis (FFT) and further advanced analysis, etc. pinpoints 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 step, (such as missing honing for example).
The introduction of a worldwide QTC calibration system permits vibration equipment to be set to operate according to international standards. |
