How to prevent bearing rust?

Bearings are an indispensable part of mechanical equipment, but they can easily rust in humid, corrosive environments or when exposed to the air. Rust will cause bearing wear and precision loss, and ultimately affect the normal operation of the equipment.

Therefore, taking effective anti-rust measures is crucial to extend bearing life and improve equipment reliability. There are many factors that affect the service life of bearings. Rust is a very important reason. Here are several ways to prevent bearing rust:

1.Surface cleaning: Cleaning must be carried out according to the properties of the surface of the object to be rusted and the prevailing conditions, and the appropriate method must be selected. Commonly used methods include solvent cleaning, chemical cleaning and mechanical cleaning.

2.Surface drying: After cleaning, it can be dried with filtered dry compressed air, or dried with a dryer at 120-170 ℃, or wiped dry with clean gauze.

3.Soaking method: Some small items are soaked in anti-rust grease, and a layer of anti-rust grease is adhered to the surface of the cross-tapered roller bearing. Oil film thickness can be achieved by controlling the temperature or viscosity of anti-rust grease.

4.Brushing method: Used for outdoor construction equipment or products with special shapes that are not suitable for soaking or spraying. When brushing, care should be taken not only to avoid accumulation but also to prevent missed coating.

5.Spray method: Some large anti-rust objects cannot be oiled by immersion. Turntable bearings are generally sprayed with filtered compressed air at a pressure of about 0.7Mpa in a clean air place. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but complete fire prevention and labor protection measures must be adopted.
