S0910-Ⅲ Bearing Vibration Meter

The S0910-Ⅲ measuring instrument is a specialized device used to measure the vibration acceleration of deep-groove ball bearings and angular contact ball bearings with inner diameters less than 65 mm. It has been widely adopted in the bearing industry.
The S0910-Ⅲ measuring instrument consists of five main components: the spindle system, the sensor adjustment device, the axial loading device, the accelerometer, and the electronic measurement instrument.
The S0910-Ⅲ meter simultaneously displays the root-mean-square (RMS) decibel level and the peak decibel level within the 50 Hz to 10 kHz frequency band. The RMS decibel level generally reflects the overall magnitude of bearing vibration, while the peak decibel level indicates the maximum amplitude of sudden changes in the vibration signal caused by factors such as manufacturing defects, impact damage, and impurity contamination—thus providing a microscopic view of the bearing’s vibration intensity. The difference between the peak and RMS levels, to a certain extent, reflects the level of abnormal noise generated by the bearing. During vibration measurement, the bearing’s vibration noise can be heard very clearly and realistically, and through an oscilloscope, one can observe the real-time waveform of the bearing’s vibration.
The shaft system of the S0910-Ⅲ measuring instrument features high-precision hydrodynamic liquid lubricated bearings. The drive shaft and the measurement shaft are arranged separately. The drive shaft is connected to the motor, while the measurement shaft is coupled to the bearing under test. The measurement shaft is connected to the drive shaft via a coupling, with the aim of enhancing the rotational accuracy of the measurement shaft. The shaft system has a clearance fit with the housing, and a grinding process is employed during manufacturing. The electronic measuring instrument incorporates weak-signal processing technology and shielding techniques, providing strong anti-interference capabilities.
The S0910-Ⅲ measuring instrument features stable readings, excellent repeatability, and clear noise detection, placing it at a relatively advanced level within China.
