In a sunny life, use a screwdriver to remove the grease, and then fly to 45 degrees. Compared with the sun, observe the droplet condition. In the sun, you can clearly see that there is no debris in the grease is the best, and it can work again. When there are too many debris, the grease must be replaced.

How to check whether the imported bearing lubricating grease is moldy
1. Sunlight exposure method
In a sunny life, use a screwdriver to remove the grease, and then fly to 45 degrees. Compared with the sun, observe the droplet condition. In the sun, you can clearly see that there is no debris in the grease is the best, and it can work again. When there are too many debris, the grease must be replaced.
2. Droplet imprint method
Take a clean white filter paper, and a few drops of oil will leak on the filter paper. After the grease leaks, if there is black powder on the surface, there is a sense of resistance when it comes into contact with the hand, indicating that there are many residues in the grease, the grease is not powdery, dry and clean, and the imprint is light yellow.
3. Oil drainage observation
Take two beakers, one filled with grease for inspection, and one empty on the table. Move the beaker filled with oil 30 to 40 cm from the table and tilt it to allow the grease to flow into the empty cup and observe its fluidity. High-performance price-performance grease should be long, thin, uniform and continuous. If the grease is discharged quickly and slowly, it means that the grease is moldy.
4. Hand twisting method
Twist the grease between the thumb and ring finger and grind continuously. The grease feels good, has good wettability, less wear debris, and no friction. If you feel a lot of friction between your fingers like sand, it means there is a lot of residue in the grease and it cannot be reused. Replace with new grease.

Popularization of professional knowledge on disassembly and assembly methods for routine maintenance of imported bearings

The disassembly and assembly of imported bearings is carried out during regular inspections and replacement of bearings. After disassembly, if the bearing is used again or the condition of the bearing needs to be checked, its disassembly and installation should be the same as before. Pay attention to the fact that the bearing parts are not damaged, especially the difficulty of the replacement operation of the bearing assembly.

FAG imported bearing seat seal failure reasons and improvement solutions

FAG imported bearing seat seal failure reasons and improvement solutions

The FAG imported bearing seat seal improvement plan "multi-stage pressure relief sealing technology" experimental bearing seat seal ring can reduce the lubricating oil leakage by reducing the pressure difference at both ends of the seal in a working environment without large-scale disassembly such as shaft extraction, and at the same time, the residual leaked lubricating oil flows back to the oil tank to achieve the purpose of shaft seal leakage prevention.

Three methods to find SKF bearing faults

Three methods to find SKF bearing faults

SKF bearings may have one or another fault during operation. After the fault occurs, we need to find out the cause of the fault to prevent similar faults from happening again in the future. So what are the methods for finding faults after a fault? Let's take a look at them together.
