How to protect bearings from rust
Bearing belongs to metal products, metal corrosion is caused by a variety of internal and external factors, we can through certain methods to prevent and slow down the corrosion of bearing products.
The appropriate method of cleaning must be selected according to the nature of the surface and the prevailing conditions.Commonly used methods are solvent cleaning, chemical cleaning and mechanical cleaning.
After cleaning, dry with filtered dry compressed air, or dry with a dryer of 120~170℃, or dry with clean gauze.
Apply antirust oil method
1) immersion method: some small items are immersed in anti-rust grease to make its surface adhere to a layer of anti-rust grease.Oil film thickness can be achieved by controlling the temperature or viscosity of the antirust grease.
2) brush painting method: it is used for outdoor construction equipment or products with special shapes that are not suitable for soaking or spraying. When painting, attention should be paid not only to avoid accumulation, but also to prevent leakage.
3) spray method: some large anti-rust materials cannot be coated with oil by immersion method. Generally, filtered compressed air with a pressure of about 0.7mpa is used for spraying in clean air places.The spray method is suitable for solvent diluted antirust oil or thin layer antirust oil, but must adopt perfect fire prevention and labor protection measures.
Environmental temperature and humidity are important factors affecting bearing corrosion.
Human sweat also rusts the bearings, so avoid direct contact during installation.
