ZXZ developed G series bearings, including single groove Ball Bearings with seal sand shields etc. Compared with the normal bearings, the torque of G series bearings are reduced by 30%and the fatigue life expectancy increased by 1.5 times.
Bearing vibration is closely related to bearing noise. In general a rolling bearing does mot generate noise by itself. What is perceived as [bearing noise" is in fact the audible effect of the vibrations generated directly or indirectly by the bearing on the surrounding structure. Therefore, vibration is the root cause of noise, while noise is the reflection of the vibration.During the bearing manufacturing & inspection, bearing noise can be controlled through strict control on the vibration.
