Solve The Problem Of Nsk Bearing Intrinsic Noise

Intrinsic Noise

It often affects the noise of the whole machinery. Reducing the raceway noise can reduce the Intrinsic Noise noise of the whole machinery.

Impact sound of rolling element and its control method when the ball NSK bearing or cylindrical roller bearing of larger model runs at low speed under pure radial Intrinsic Noise load, due to the small centrifugal force of the rolling element,

the rolling element in the non load area will impact the cage or raceway and make noise. But as the speed increases, the sound will disappear. The control Intrinsic Noise methods of impact sound of rolling elements include: appropriately reducing radial clearance and using NSK bearing with cage with reasonable structure and flexible material.

Rolling sound of NSK bearing and its control method rolling sound is the harsh metal friction sound that can occur in cylindrical roller bearings on all occasions. Most of it occurs in grease lubricated larger NSK Bearings, which is more likely to occur in greases with degraded base oil performance, and almost does not occur in oil lubrication.

Solve The Problem Of Nsk Bearing Intrinsic Noise

In addition, it is easy to occur in Intrinsic Noise winter. When bearing pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a specific speed range with the different model and size of NSK bearing,

which will occur continuously and intermittently. Taking special Intrinsic Noise processing methods for the outer race raceway can prevent the occurrence of rolling sound.

If necessary, this NSK bearing can be selected, or the radial clearance of NSK bearing can be Intrinsic Noise appropriately reduced, the lubricating grease with excellent performance can be used and the rigidity of parts matched with NSK bearing can be improved.

Introduction to common damage causes of Koyo bearing

Imported Bearing Running Track Method

Most Koyo bearings are damaged for many reasons, such as Intrinsic Noise exceeding the original estimated load, ineffective sealing, too small Koyo bearing clearance caused by too tight fit, etc.

Any of these factors has its Intrinsic Noise special damage type and will leave special damage traces. Therefore, by examining the damaged Koyo bearing, the possible causes can be found in most cases.

Generally speaking, one third of the damage of Koyo bearings is due to fatigue damage, the other one third is due to poor lubrication, and the other one third is due to the entry of pollutants into Koyo bearings or improper installation and treatment. However, these forms of damage are also related to industrial differences.

For example, the pulp and paper industry is mostly due to the damage of Koyo bearings caused by poor lubrication or pollution, rather than material fatigue; Koyo bearings used by general manufacturing enterprises are mostly caused by fatigue.

Not only valuable Koyo bearings need maintenance, but also ordinary Koyo bearings. After all, a small screw will affect the overall situation. If you want your Koyo bearings to be used for a long time, please pay attention to these aspects often.
