What Are The Adverse Effects Of Cleanliness On NSK Bearings?

wallpapers News 2020-04-01

NSK bearings are essential parts of machinery and equipment. Maintaining cleanliness can better improve work efficiency and ensure the movement of the machine. The primary function is to support the mechanical rotating body, reduce the friction coefficient during its progress, and ensure its rotation accuracy.

1. Impact on bearings life

The cleanliness of the bearings has a considerable effect on the life of the needle bearing. The bearing has been tested for this purpose. The result is that the difference is several times or even dozens of time. The higher the cleanliness of the bearings, the longer the life, and so on. Tests by others have shown that different cleanliness of the lubricant has a significant impact on the life of the ball bearing. Therefore, improving the purity of the lubricating oil can extend the life of the bearing. Also, if the dirt particles in the lubricating oil are controlled below 10um, the bearing life will increase several times.

2. Impact on vibration and noise

The test results of the bearing test center show that cleanliness seriously affects the vibration level of the bearing, especially in the high-frequency band.

Bearings with high cleanliness have low vibration velocity values, especially in high-frequency bands. The effects of dust in a needle bearing grease on noise have been tested, and it is proved that the more dirt, the louder the sound.

3.Effect on lubrication performance

The decrease in bearing cleanliness not only affects the formation of lubricating oil films but also cause the deterioration of the grease and accelerate its aging, which affects the lubrication performance of the grease. The oil seal is a very fragile parts, so do not apply excessive force when inspecting and disassembling the NSK bearings to avoid damage to the elements. If the NSK bearings oil seal and its surrounding regions show adverse symptoms, be sure to replace it, to prevent the destruction of the NSK bearings due to the lousy oil seal.
