Quạt Rà Bạc Đạn

Quality bearings are subjective. While you may not want cheap, oil or greaseless bearings for anything with a load, using them for a fidget spinner is ideal. Instead of spending money on super good bearings and then washing the grease out, why not add some clean wear on some cheaper ones?!

Just assemble the main peg with the bearing and cap screwed in and push the fan down onto the bearing. Take the whole mechanism to your car, roll down your window half way and slide the mount onto the back end of your window. Then, roll up the window to lock it in place and drive around!

After driving to work and back for 2 days (about 40 miles total) I had tripled my spin times!

I have noticed with the bearings I have been using that after some time in this fan apparatus, the balls seem to become more polished. I also tried using some toothpaste to see if I could get an even better spin. So far, I think clean and dry is better than using toothpaste or another hydrolyzed silica compound.
