Using the skf bearing, the grease is critical. If deterioration of grease, not only to achieve its proper role away will damage the bearings.
① oil flow observation
Take two measuring cups, one of Sheng to be checked lubricants, and other empty on the table will be filled with lubricating oil measuring cup held high to leave the desktop 30-40 cm and tilt, so that the lubricating oil to slowly flow to the empty cup observe the flow, the quality of a good lube oil flow should be slender, uniform, continuous, if there is oil flow unsteadiness, sometimes with large shed, said lubricating oil has gone.
② hand twist
Twist the lubricant between the thumb and index finger repeatedly grinding, better lubricants hand felt lubrication, less wear debris and friction-free, if they feel the sense of a larger friction of the sand and the like between the fingers, indicates that the lubricant within the impurities can not be reused, should be replaced with new lubricants.
③ illumination method
On a clear day with a screwdriver lubricant pulled up a 45 degree angle with the horizontal plane. Control sunlight, observed droplets circumstances, in light, you can clearly see the lubricant wear debris as well, can continue to effect if too much debris, replace grease.
(4) droplets traces of France
Take a clean white filter strip, drip a few drops in the filter strip, until the lubricant leakage, if the surface of a black powder, touch resistance astringent, then the lubricant inside the impurity has a lot of good lubricant powder, hand feels dry and smooth, and yellow traces.
