The storage of automotive wheel hub bearings should pay attention to the following points:
1. Dust prevention technology: The storage location and conditions of bearings should be cool, dry, and well ventilated, and dust should be minimized as much as possible. Dust prevention measures mainly rely on dust prevention structures and covers, with sealing devices and covers being important parts. When stored for a long time, the temperature should be uniform and the temperature change should be less than 8 ° C.
2. moisture-proof technology: To avoid dampness, the humidity in the storage location should be maintained at an appropriate level and regularly checked to ensure a dry environment.
3. Rust prevention technology: The rust prevention period for bearings that need to be installed and used in the short term is six months. Generally, the starting date for calculating the rust prevention period of bearings is based on the date indicated on the product's factory certificate of conformity. The oil seal packaging of the bearings should be checked regularly. If rust is found, the oil seal packaging should be repackaged.
4. Anti vibration technology: The storage area should be vibration free, avoiding direct sunlight on the bearings, and at the same time, preventing bearings from falling and being damaged.
5. Anti deformation technology: Bearings should be placed on wooden supports that are at least 02m away from the ground to prevent deformation.
6. Anti wear technology: It is necessary to regularly inspect and maintain the bearings, keep the sealing device intact, and use bearing dust covers, which can effectively prevent dust from entering the bearings and extend their service life.
7. Anti aging technology: It is necessary to regularly inspect the use of bearings, conduct surveys, statistics, and comparative analysis, summarize experience, in order to improve the supply, inventory, use, and selection of bearings.
8. Anti damage technology: During use, it is necessary to regularly inspect and maintain the bearings to prevent abnormal noise, vibration and deformation, high temperature, and ensure quality accuracy. At the same time, it is necessary to check gear engagement, transmission ratio, brake sensitivity and reliability, tire pressure, etc.
