Raceway sound is due FAG rolling bearing rotation scroll through the raceway and inspire a kind of smooth and continuous noise, only when its sound pressure level or tone only when aroused great attention. In fact, inspired raceway sound acoustic energy is limited, as in normal circumstances, high-quality sound of 6203NTN bearing raceway 25 ~ 27dB. This noise to withstand the radial load FAG bearings for the most typical, the following Wuxi Gurit tell you what this raceway noise characteristics:

     A vibration frequencies above 1kHz;

     2 Noise, vibration is random;

     3 FAG bearing stiffness increases, the total sound pressure level is lower, even if the speed increases, the total sound pressure level has also increased little;

     4 speed regardless of how changes in the main frequency noise is almost constant with the speed and the sound pressure level is increased with the increase;

     5 the higher viscosity of the lubricant, the lower the sound pressure level, but for grease lubrication, the viscosity, soap can affect the shape and size of the fibers noise value;

     6 When the radial clearance increases, the level will increase dramatically.
