How to check whether SKF Bearing Grease is deteriorated

method to check whether SKF Bearing Grease has deteriorated:

grease is very critical in the process of using SKF bearings. If the deteriorated grease is used, it will not only fail to play its due role, but also damage the bearing

1. Oil flow observation method: take two measuring cups, one of which is filled with lubricating oil to be checked, and the other is empty on the desktop. Lift the measuring cup full of lubricating oil cm away from the desktop and tilt it. Let the lubricating oil flow slowly into the empty cup, and observe its flow. The lubricating oil with good quality should flow slender, uniform and continuous. If the oil flow is fast or slow, and sometimes large pieces flow down, it is said that the lubricating oil has deteriorated

LEGO said 2. Hand twisting method: twist the lubricating oil between thumb and index finger and grind it repeatedly. A better lubricating oil hand feels lubricated, with less wear debris and no friction. If it feels a large friction feeling such as sand between fingers, it indicates that there are many impurities in the lubricating oil and it can't be used again. It should be replaced with a new lubricating oil. Import pump valve

3. Illumination method: on sunny days and the special experimental air of some products, use a screw to check the shell, fix a stationary screwdriver to lift up the lubricating oil, and form an angle of 45 degrees with the horizontal plane. Compare with the sunlight and observe the oil drops. Under the sunlight, it is good to see that there is no wear debris in the lubricating oil. It can continue to function. If there are too many wear debris, replace the lubricating oil

4. Oil drop trace method: take a clean white filter paper and drop several drops of oil on the filter paper. After the lubricating oil leaks, if there is black powder on the surface and there is an astringent feeling by hand, it means that there are a lot of impurities in the lubricating oil. Good lubricating oil has no powder, and it is dry and shiny by hand, just like sheared vines, which are slippery and show yellow traces
