Maintenance method of thin wall bearing

Thin wall bearing not only realizes the extremely thin bearing section, but also realizes the miniaturization and lightweight of products. The diversity of products expands its scope of use. The specific maintenance methods are as follows:
1. Remove the bearing. Some bearing side covers are removable, others are not
2. If it's detachable, it's very simple! Use a slotted precision screwdriver to pry up the C ring at the gap of the C ring, and then take down the side cover. Just remove one side! C-ring and side cover should be put away. After washing, you "may" want to install them back!
3. If it is not detachable, it will be more troublesome! Use destructive methods. Use a precision screwdriver to reach into the seam of the side cover and pry the side cover up. Don't doubt it. That's it, but the side cover can't be installed back! Well, throw it away! Remember, just remove one side and destroy both sides!
4. Remove the side covers of all bearings and start washing! Pour the oil stain into the bowl, throw the bearing down and stir it.
