Bearings in many industries have an important role, such as automobile, subway, became an essential part of the bearing.
In the bearing during use, corrosion phenomenon often occurs, which was troubled by many friends, then what factors can easily lead to corrosion of KOYO bearings? experts point out that cause corrosion of bearings for a number of reasons, including internal and external causes.
Summarized as follows:
1, environmental impact. Changes in temperature and humidity will be brought in by.
2, the metal itself. Metals surface finish as well as factors such as structural elements in the composition of the metal itself.
3, environmental media. Metal surfaces exposed to the environment and the media, will produce chemical reactions such as oxidation, which can lead to bearing corrosion.
4, human sweat. PH value 5-6 of human sweat, easily lead to bearing corrosion, so will not break in direct contact with your hands.
Lead bearing rusty for a number of reasons, but the remedy to early prevention can also be effective away from the bearing trouble of corrosion. The following summarizes several preventive measures:
KOYO bearings rust?
1, surface clean and dry. First of all, clean the bearing surfaces, solvent cleaning, machine cleaning and chemical treatments and other means. After cleaning the surface to dry, or dry with the dryer, and finally dry.
2, coating antirust oil. You can soak, brush, spray method, in KOYO bearing surface with a layer of anti-rust grease, which can play a role of isolated air, preventing oxidation. However, this method requires focus on fire protection measures.
