Therefore, the design and installation of the bearing assembly department to adequately studied, in accordance with the operating standards. Operating standards projects typically as follows:

1. Clean NSK bearings and related components
2. Check the size and precision of related parts
3. Install
4. After checking the bearing installation
5. fill lubricant
I hope in the installation, and then open the bearing package. When the general grease lubrication, no cleaning bearings, grease filled directly. When oil lubrication, generally do not have to clean, but the instrument used or high-speed bearings, etc., use clean oil cleaning, removing rust coating on the bearing agent.
