SpinnerHub sells a large variety of fidget spinners and we are very serious about our bearings! These Hybrid Ceramic R188s with Silicon Nitride balls are the absolute top of the line in fidget spinner bearings. Most new spinners come with R188 bearings because their smaller size allows for longer spin times. These will be an upgrade for any spinner with a stainless steel R188 bearing and they are perfect to have around in case your fidget spinner bearing gets dirty or breaks. Prime shipping means it will arrive super fast. Please don't hesitate to contact us with any questions!
