Zealous Bearings are one of the most popular bearings in the industry. With built-in speed rings, and spacers at a precise .4045" these bearings eliminate all slop in your wheels for smooth rolling and predictable slides. They're lubed with nanoceramic grease that finds all of the small dings in the ball bearings, fills them in, and corrects the bearings for a frictionless roll. This equates to a fast, smooth, and long lasting, self-fixing bearing. Equipped with ceramic balls, these are lighter, stronger, and faster than your standard steel bearings. With durability and speed in mind, the Zealous Ceramic Built In Bearings are one of the damn finest out there.
