Miniature ball bearings, inner diameter 1mm, outer diameter 3mm, with a cage, the advantage of having a cage is that the balls will not move, the clearance of the inner and outer rings is smaller, the force is more uniform, and the gearbox with bearings in our store has also been upgraded to this kind of bearing!
