Solve the problem of nature of NSK bearing noise - bearing knowledge

Often affect the mechanical noise, reduce noise can reduce the mechanical noise. Impact of the rolling element and its control method for larger models of NSK bearings or ball speed cylindrical roller bearing under pure radial load, due to the centrifugal force is small roller, the load of rolling body will impact cage or race and making noises. But with the increase of rotational speed, the noise will disappear. Control method of rolling body impact sound: decrease the radial clearance, use with reasonable structure and material with kindliness NSK bearing retainers. NSK bearings of rolling mill and its control method for roll is cylindrical roller bearing in the harsh metal can occur in all occasions, mostly happens in the NSK bearing grease lubrication of the larger models, and in the performance degradation occurred more often in grease base oil, almost does not occur when oil lubrication. In addition, more easily occur during the winter, when under pure radial load, the radial clearance prone to big occasions, NSK bearing type and with different size, easy to happen in a certain speed range, both continuous and intermittent. External ring raceway take special processing method can prevent the occurrence of roll ring, if necessary, can choose the NSK bearings, NSK bearings or appropriate to reduce the radial clearance, the use of high performance grease and improve NSK bearings with matching parts rigidity.
