1. Wipe the cleaned fag bearing dry with dry rags, and then soak it in antirust oil. In this process, the fag bearing should be completely in contact with the antirust oil and rotate the fag bearing Maintain Fag continuously, so that the oil film formed by the antirust oil can cover the surface of the fag bearing and achieve the purpose of antirust.
2. First, put the fag bearing into gasoline for cleaning, wipe off the oil sludge and dust left on the fag bearing, and gently wipe and Maintain Fag polish all rusty fag bearings with metallographic sandpaper until there is no roughness by hand.
3. Next, apply lithium grease and butter evenly on the surface of fag bearing, including inner and outer rings, wheels and cage. In Maintain Fag addition, the fag bearing is rotated while wiping, so that the butter can really enter the fag bearing to fully lubricate it.
4. The latter process is packaging. In order to save costs, we “turn Maintain Fag waste into treasure”, cut the discarded cement packaging bags in the warehouse into packaging bags of appropriate size, wrap fag bearings tightly, mark the specifications and models of fag bearings, and then put them back on the shelf for storage.
NSK Bearings will encounter various problems during use. Maintain Fag Today, let’s learn how to check the deterioration of NSK bearing grease.
In the process of using NSK Maintain Fag Bearings, grease is very critical. If deteriorated grease is used, it will not only fail to play its due role, but also damage NSK Bearings.
① Oil flow observation method
Take two measuring cups, one Maintain Fag containing the lubricating oil to be checked and the other empty on the table. Lift the measuring cup filled with lubricating oil 30-40 cm away from the table 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, Maintain Fag uniform and continuous. If the oil flow is fast and slow, sometimes large pieces flow down, The lubricating oil has deteriorated.
② Hand twisting
Twist the lubricating oil between the thumb and index finger and grind it repeatedly. The better lubricating oil hand feels lubricity, less wear debris and no friction.
If it feels a large friction feeling such as sand particles between the fingers, it indicates that there are many impurities in the lubricating oil and it can not be used again. It should be replaced with a new lubricating oil.
③ Illumination method
On sunny days, lift up the lubricating oil with a screwdriver at an angle of 45 degrees to the horizontal plane. Observe the condition of oil drops according to the sunlight. In the light, it can be clearly seen 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 a sense of astringency by hand,
it indicates that there are many impurities in the lubricating oil. Good lubricating oil has no powder, and it is dry and smooth by hand and shows yellow traces.
