When using bearing parts, many customers will find that spots or discoloration symptoms will occur on the bearings. The emergence of these symptoms cannot operate normally, which will directly affect the use effect and service life of the bearings. Therefore If the process of the bearing appears or discolored, we must perform the next test or find the corresponding solution.
What are the symptoms of spots in the bearing?
When the bearing appears, the color of the roller is mainly dull and the spots on the surface of the road, and the spots are pitted.
We will share the method of improving bearing spots: improving sealing effects, lubricating oil filtration, and improving the lubrication system.
Why does the bearings change color? What's the reason?
Common factor of bearing coloring: changes in surface color, foreign body entry, adverse lubrication conditions, and color changes in the form of fire in the form of bearing caused by overheating, and oil deposits on the bearing surface.
We will share the method of improving bearing coloring:
1. Use organic solvents to remove deposited oil (oxalic acid).
2. If the rough surface is polished by sandpaper and cannot be removed, the discoloration is rust or corrosion. If it can be completely removed, the discoloration is formed by the recovery of the discoloration surface due to overheating.
