Several Requirements For Cleaning Contaminated And Rusted Skf Bearings

Contaminated And Rusted 

Washing oil, gasoline, ethanol, dehydrated liquid, neutral or alkaline cleaning agent can be Contaminated And used to clean SKF bearings. However, it should be noted that “gasoline, washing oil, ethanol and dehydrated liquid are inflammables; alkaline cleaning agents are corrosive.

The use of hydrogen chloride solvent oil is dangerous to combustion, explosion and Contaminated And decomposition, and may also be harmful to health. When cleaning SKF bearings, tools such as pointed brush, flat brush or non fiber fabric can be used. Once the solvent volatilizes after cleaning,

the SKF bearings shall be coated with antirust oil immediately. When there is hardened oil or grease residue on the SKF Bearing, the SKF Bearing can be cleaned mechanically first, and then treated with aqueous solution of strong alkaline substances.

1. In the process of producing bearings, some enterprises did not strictly follow the requirements of cleaning and antirust procedures and oil seal antirust packaging to carry out antirust treatment on the bearing parts in the processing process and the finished SKF Contaminated And bearings after assembly.

For example, the turnover time of the ferrule in the turnover process is too long, and the outer circle of the outer ring is in contact with Contaminated And corrosive liquid or gas.

2. The quality of antirust Contaminated And lubricating oil, cleaning kerosene and other products used by some enterprises in production can not meet the requirements of process and technology regulations.

3. As the price of SKF Bearing Steel has fallen again and again,

the material of bearing steel has gradually declined. For example, Contaminated And the content of non-metallic impurities in steel is high

(the increase of sulfur content in steel reduces the corrosion resistance of the material itself), metallographic structure deviation, etc. At present, the sources of bearing steel used by production enterprises are miscellaneous, and the steel quality is fish dragon mixed beads.

4. The environmental conditions of some enterprises are poor, the content of harmful substances in the air is high, and the turnover Contaminated And site is too small to carry out effective antirust treatment. In addition, the hot weather and the violation of rust prevention regulations by production workers also exist.

5. Some enterprises’ SKF Bearing packaging materials such as antirust paper, nylon paper (bag) and plastic cylinder do not meet the requirements of antirust packaging of rolling bearing oil seal, which is also one of the factors causing corrosion.

6. The turning allowance and grinding allowance of SKF Bearing Rings in some enterprises are too small, and the oxide scale and Contaminated And decarburization layer on the outer circle cannot be completely removed is also one of the reasons.
