What method do bearing manufacturers use to prevent rust?
The last article talked about how bearing manufacturers should do a good job of bearing rust prevention. In this article, I will explain in detail what methods bearing manufacturers use to prevent rust. 1. Surface cleaning method; The cleaning method must be selected according to the characteristics and conditions of the anti-rust surface. Commonly used are organic solvent cleaning method, organic chemical solution cleaning method and mechanical equipment cleaning method. When the surface is dry and clean, it can be compressed and dried with filtered dry air, or used in an air dryer at 120~170°C, or wiped with a clean gauze. 2. The method of applying anti-rust oil (1) Immersion method: the bearing manufacturer will soak the bearing in anti-rust grease, so that a layer of anti-rust vegetable grease will adhere to the surface. The thickness of the grease can be done according to the temperature or viscosity of the anti-rust vegetable grease. (2) Brushing method: It is used for large and medium-sized bearings that are not suitable for soaking or painting. When brushing, not only should pay attention not to cause deposition, but also pay attention to avoid missing coating. (3) Sprayer method: The large and medium-sized bearings of some bearing manufacturers cannot use the soaking method to apply oil. Generally, spray painting is carried out in the gas cleaning area with filtered air compression with a working pressure of about 0.7Mpa. The sprayer method can use organic solvent diluent type antirust oil or chromatography antirust oil, but be sure to use sound fire safety and work security measures.
