Quantum Diamonds Ceramic Bearings

These bearings use zirconium oxide ceramic balls paired with chrome steel raceways. This hybrid design gives you the speed and heat resistance of ceramic while maintaining the structural durability of steel, making them ideal for high-impact skating.

Yes, the coating is specifically engineered to resist environmental wear. It adds a layer of protection against moisture and grit, which helps the bearings stay smooth even when you're skating in less-than-ideal conditions.

The proprietary Graphflo lubricant is designed for low maintenance, but performance will eventually depend on your environment. If you skate in dusty or wet conditions, you should clean them and apply a fresh drop of lubricant whenever you notice a drop in roll speed.

Yes, these are standard 608-size bearings, which fit virtually all modern skateboard wheels. The included speed washers help ensure a proper fit and reduce friction against your axle nuts.

The cage holds the ceramic balls in place. Using a high-strength thermoplastic rather than metal makes the bearing more resistant to impact and deformation, which is crucial if you frequently land hard or skate rough terrain.

The kit comes with a full set of eight bearings, 16 frictionless shields, eight speed washers, and a 2ml tube of Graphflo lubricant. It provides everything you need for a complete setup and future maintenance.
