How to keep bearings better?

The bearings are coated with an appropriate amount of rust preventive oil and packaged with rustproof paper. As long as the package is not damaged, the quality of the bearing will be guaranteed.
However, for long-term storage, it is recommended to store on a shelf 30 cm above the ground under the conditions of humidity below 65% and temperature of about 20 °C. In addition, the storage place should avoid direct sunlight or touch the cold wall.
Bearing packaging
The packaged inner and outer packaging bearings are cleaned and rust-proofed after being manufactured and tested, and then placed in the inner packaging to achieve waterproof, moisture-proof, dust-proof, shock-proof, and maintain bearing quality and precision. And for the convenience of use and sale purposes.
The inner packaging of the bearing is divided into three categories according to the anti-rust period:
1 Short anti-rust period packaging: anti-rust period of 3 to 6 months, suitable for large-volume delivery to the same subscriber, the bearings will be put into use in a short period of time. According to the agreement between the two parties, the principle of convenient use is adopted, and simple packaging is adopted.
2 general anti-rust period packaging: anti-rust period of one year, suitable for general purpose bearings.
3 long anti-rust period packaging: anti-rust period of two years, suitable for special and precision bearings.
The inner packaging materials of the bearing are polyethylene plastic tube (box), kraft paper, plain and crepe polyethylene composite paper, carton, polyethylene or polyethylene plastic film, nylon fastening tape or plastic fastening tape, waterproof high-strength plastic tape. , linen bags, etc. All of the above materials are required to ensure the corrosion resistance test of the material is qualified.
