Amp bearings are the epitome of durability and speed. These high-quality gold ceramic bearings are strong enough, fast enough, and more than resilient enough to help you carve or cruise your own path. These bearings feature silicon nitride ceramic balls and have the lowest tolerances up to 0.01 micron to make sure your board doesn't slow you down. Lighter and faster than steel ball bearings and with an oil-free raceway, these Amp bearings are your ideal prescription for speed. Includes a full set of 8 bearings and 4 spacers.
