6238 Single Row Deep Groove Ball Bearing

It is found that the low frequency measurement of common Deep Groove Ball Bearing is higher than that of foreign low noise Deep Groove Ball Bearing. Through vibration speakers sound, most of them are in normal rustling with some low frequency sound, such as: the eccentric exercise "CAM", "buzzing" sound, rapid train "to eat" and other low audio noise. Low - noise bearings abroad generally have low - frequency measurement values and no heterophony. Based on the analysis of bearing vibration and noise, as roundness error of channel, due to the defects generally lower than 15 waves, belong to low wave produced by the vibration frequency is generally in low frequency range, and the vibration amplitude is small, belongs to the low frequency vibration low-rising. It can be seen from the sound intensity that the vibration of low frequency and low amplitude produces low sound intensity, which is generally not felt by the human ear. However, when the roundness deviation is large, and its shape wave number is more than 3 waves, its low-frequency value is large, and other low-frequency sound will be produced at the same time.
