Jarring sound and control sound jarring INA bearing is a cylindrical roller bearing in mind the harsh tone metal friction all occasions that might occur roller bearings wholesale, mostly in larger models grease lubricated bearings in roller bearings , but more likely in the base oil performance degradation of grease, almost does not occur when the oil lubrication. In addition, more prone to winter, when subjected to pure radial load spherical roller bearings price, the radial clearance prone to big occasions and in different sizes depending on model, at a particular speed range content and easy occurs, both will occur continuously intermittent. Raceway sound is due to the rotating rolling element bearing NTN rolling in raceway and stimulate a smooth and continuous noise, the level or tone when aroused great attention only when. In fact, inspired by the raceway sound acoustic energy is limited, as in normal circumstances, bearing raceway sound quality is 25 ~ 27dB. This noise with radial load single row deep groove ball bearings for the most typical, it has the following characteristics: a noise, vibration is random; b vibration frequencies above 1kHz; c regardless of how changes in speed, noise main frequency. The sound pressure level is almost constant increases with the speed increase; when the radial clearance increases, a sharp increase in the sound pressure level d;. e NTN bearing rigidity increases Spherical roller bearings sales agents, the total sound pressure The lower the level, even if the speed increases, the total sound pressure level increases is not; the higher the f viscosity of the lubricant, the sound pressure level is lower, but for grease lubrication, its viscosity, soap fiber shape and size can affect the noise value.
