The rust prevention of HONB bearings is very important. Here are some common methods of bearing rust prevention.HONBbearing07
1. Surface cleaning: Cleaning must be based on the nature of the surface of the rust-prevented object and the prevailing conditions, and an appropriate method must be selected. Commonly used are solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method.
2. After the surface is dried and cleaned, it can be dried with filtered dry compressed air, or dried with a dryer at 120-170 ℃, or dried with clean gauze.
3. Soaking method: Some small items are immersed in anti-rust grease, and the cross tapered roller bearing is coated with a layer of anti-rust grease on the surface. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease.
4. Brushing method: It is used for outdoor construction equipment or special-shaped products that are not suitable for immersion or spraying. When brushing, it is necessary to pay attention not to accumulate, but also to prevent leakage.
5. Spray method: Some large anti-rust objects cannot be oiled by immersion method. Bearings are generally sprayed in clean air with filtered compressed air with a pressure of about 0.7Mpa. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but complete fire protection and labor protection measures must be adopted.
It should be noted that the following acid solutions cannot be used for bearing rust removal: sulfuric acid, hydrochloric acid, dilute sulfuric acid, and dilute hydrochloric acid. Because these acids will destroy the good metal parts, these kinds of liquids must not be used!
