The bearings are coated with an appropriate amount of anti-rust oil and packaged with anti-rust 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 30cm above the ground under the conditions of humidity below 65% and temperature around 20 degrees Celsius. In addition, the storage place should avoid direct sunlight or contact with cold walls.
