Do you believe that the failure of bearings can be determined by the change in grease at a glance? Let's take a look at the following situation together.
Darkening of oil color: Normal oil is bright and free of impurities, except for its own dark color.
If the color of the oil becomes darker, it indicates that it has worked at high temperatures, causing the oil to be oxidized and carbonized.
The oil becomes cloudy:
If there is turbidity in milk or oil, it indicates that water has entered the content, and the oil will become this phenomenon. It is necessary to check whether it is well sealed, sealed, humidity, etc. If conditions permit, it is necessary to test the oil separation and the proportion of water components.
Greasing and darkening:
If the grease is dull and dull when opened, it indicates that the base oil inside the bearing has been depleted and needs to be added as soon as possible.
Changes in oil taste:
The lubricating grease inside the bearing is severely oxidized, and it needs to be replaced immediately.
