Solve the essential noise problem of NSK bearings
Often affecting the noise of the entire machine, reducing the sound of the raceway can reduce the noise of the entire machine.
Impact sound of rolling element and its control method When a larger type of ball NSK bearing or cylindrical roller bearing runs at low speed under pure radial load, the rolling element in the non-loading area will be impact-maintained due to the small centrifugal force of the rolling element. Noise caused by racks or raceways. But as the speed increases, the sound will disappear. The control methods for the impact sound of the rolling element are: appropriately reducing the radial clearance, and using the NSK bearing with a reasonable structure and a flexible material.
The rolling noise of NSK bearing and its control method The rolling sound is the harsh metal friction sound of cylindrical roller bearing which can occur in all occasions. Most of them occur in the grease-lubricated NSK bearing, but the base oil performance deteriorates. Grease is more likely to occur and hardly occurs when oil is lubricated.
In addition, it is more likely to occur in winter. When subjected to pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a certain speed range depending on the size of the NSK bearing model. Continuous occurrences will occur intermittently. Special processing methods for the outer ring raceway can prevent the occurrence of rolling noise. If necessary, use this NSK bearing, or reduce the radial clearance of NSK bearings, use excellent grease and improve the matching with NSK bearings. The rigidity of the piece.
