Check whether the SKF bearing grease replacement

Grease is very important for SKF bearings, grease bearings in SKF rolling surfaces and forms a thin layer of oil film between sliding surfaces to prevent direct contact with the metal and metal, thereby reducing internal friction and wear of SKF bearings to prevent burning stick. If you use grease for long period of time, may cause very serious damage to SKF bearings, consequences were disastrous.
The first and simplest is a method of lighting approach
We can clear weather days, SKF bearing lubricant stir with a screwdriver, and level to a 45-degree angle. The Sun, observing oil droplets, under the Sun, you can clearly see no debris in lubricating oil for good may continue to function, if excessive debris, should be replaced with oil.
Second is the oil flow observation method
We can take two a Cup, a with needs check of SKF bearing lubricants, another empty placed in desktop Shang, will loaded full lubricants of Cup cite high left desktop 25-45 cm around and tilt, let lubricants slowly stream to empty Cup in, carefully observation its flows situation, quality good of lubricants stream to Shi should is slender, and uniform, and continuous, if appears lubricants outflow Shi suddenly fast suddenly slow, sometimes also will has large together shed, is said the lubricants time has had long needs replaced has.
The third is method of oil droplets traces
You can take a piece of clean white filter paper, SKF bearing lubricant drops a few drops on the filter paper, after the oil leakage, if surface has black powder, tart touch resistance, then the Lube there are many impurities, should also replace the lubricant, General Pro-Lube powder-free, dry and smooth to touch, and traces of yellow.
Fourth hand twist method
SKF bearing lubricant can be twisted in the repeated grinding between thumb and forefinger, hand felt the lubricity of lubricating oil in General, less debris, without friction, who feel that sense of larger sand grains such as friction between the fingers, it means the lubricating oil impurities within, can no longer be used, and should be replaced when the new lubricant.
