What kind of bearings are used in Migao Saba black gold roller skates? How to maintain bearings? And how to match Saba shelves? Where can I buy them?

Actually, it will be more expensive if you don't care. Find an agent online. There are special dealers in Beijing with accessories, and you can get them by phone. To clean the bearing, first pry out the small iron ring with plastic cover with a crew cut screwdriver, then remove the plastic cover, find a bottle that can be stuffed into the bearing, put some gasoline in the bearing, shake the seal and clean it. Then take it out and air dry it, and add bearing butter between the beads. Of course, the better the oil added, the better the bearing lubricity. Then cover the plastic cover, clamp the sealing ring, and the bearing maintenance will be ok.

If you like roller skating, I suggest you go to Club 66. Student fans from all over the world meet with local fans to brush the streets together. All kinds of activities are still very good, and there are technical stickers you need.
