FAG bearing anti-corrosion measures and lubrication method

FAG bearings corrosion caused by a variety of intrinsic and extrinsic factors could be summed up:
A bearing metal surface finish (the difference of oxygen concentration cell corrosion).
2, the bearing metal material chemical composition and structure.
3, the bearing metal surface contact with the solution composition and pH value;
4, bearing the ambient temperature and humidity.
5, the bearing metal surface in contact with the various environmental media.
6, human sweat pH of 5 to 6. Therefore, in order to prevent hand sweat caused by corrosion, installation and production personnel should wear gloves, do not just hand contact with self-aligning roller bearings.
FAG bearings, grease is very critical. Deterioration of the grease, not only to achieve its proper role away will damage the bearing.
An 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 method
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 should be replaced with new lubricants.
3, the 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 the light, can clearly see the lubricant wear debris for good, you can continue to use excessive debris, replace grease.
4, the oil droplets traces of France
Take a clean white filter paper, drip a few drops on filter paper, until the lubricant leakage, if the surface has a black powder, touch resistance astringent, then the lubricant inside the impurity has a lot of good oil powder, hand feels dry and smooth, and yellow traces.
