Bearing rust is a common problem that can significantly reduce their lifespan and performance. To prevent this, several effective anti-rust methods are used depending on the type of bearing and its application environment. Here’s a detailed look at some of the most commonly used techniques.
**Surface Cleaning for Rust Prevention**
Before applying any anti-rust treatment, it's essential to ensure the surface of the bearing is clean and free from contaminants. This includes removing any existing rust, dirt, or old lubricants. There are three main cleaning methods:
- **Solvent Removal:** Using solvents like mineral spirits or alcohol to dissolve and remove oils, grease, and other residues.
- **Chemical Treatment:** Applying chemical solutions such as phosphating or alkaline cleaners to neutralize corrosion and prepare the surface for further protection.
- **Mechanical Cleaning:** Using tools like brushes, sandpaper, or abrasive blasting to physically remove rust and debris.
Once cleaned, the surface should be completely dry. This can be achieved using filtered compressed air, a heat dryer set between 120–170°C, or simply by wiping with clean cloth or gauze.
**Application of Anti-Rust Oil**
After proper cleaning, applying an anti-rust oil or grease is crucial to protect the bearing from moisture and oxidation. The following methods are commonly used:
- **Immersion Method:** Small components can be fully submerged in anti-rust grease. This ensures even coverage and allows the oil film thickness to be controlled based on the viscosity and temperature of the grease.
- **Brushing Method:** Ideal for large or irregularly shaped bearings, especially those used outdoors or in hard-to-reach areas. When brushing, care must be taken to avoid pooling or over-application, which could lead to contamination or reduced performance.
- **Spraying Method:** For large-scale applications where immersion is not practical, a fine mist of anti-rust oil is sprayed onto the surface using compressed air (around 0.77 MPa). This method works well with solvent-based or thin-layer anti-rust oils but requires strict fire safety measures and proper personal protective equipment.
By following these steps, you can effectively prolong the life of your bearings and maintain their performance under various environmental conditions.

Aluminum extrusion profiles are made into aluminum rods after aluminum ingots are melted and cast, and put into an extrusion press at a certain temperature. Under the action of strong pressure, aluminum profiles with a certain cross-section shape and size are extruded through a specific shape mold. Different alloy components have different properties. This manufacturing process gives aluminum extruded profiles a high degree of consistency and accuracy. Aluminum extruded profiles have the advantages of good corrosion, high quality, high weather resistance and strong recyclability. Classification by profile: There are a variety of different cross-section shapes, such as rectangle, circle, square and so on. Classification by alloy: common 6063, 6061 alloys, etc., different alloy components have different performance characteristics. In short, aluminum extruded profiles play an important role in many fields with its unique advantages, and with the continuous development and innovation of technology, its application prospects will be broader. An in-depth understanding of the characteristics and applications of aluminum extruded profiles helps us to make better use of this material and contribute to the development of various fields.
