Among them, the vibration parameters of bearings are one of the important indicators for judging the performance of bearings. Its product quality and manufacturing level are constantly being pushed to new heights. As an indispensable precision instrument for bearing production lines and third-party measurement units, the vibration measurement data of bearing vibration measuring instruments is an important indicator for judging the quality of bearings. At present, when conventional bearing vibration measuring instruments are relatively mature, improvements are made to the original equipment to reduce the time and difficulty of debugging instruments and speed up measurement efficiency.
