Quantum Fusion Bearing

The diamond matrix coating is primarily there to harden the surface of the raceways and rolling elements. This significantly boosts durability and provides excellent weather resistance, meaning these bearings will hold up much better than standard steel options if you occasionally skate in damp conditions or dusty environments.

Yes, the silicon nitride rolling elements are lighter and harder than steel, which reduces friction and heat buildup. You will notice a smoother, more consistent roll, especially when maintaining speed during transitions or cruising.

No, the kit is comprehensive. It includes eight bearings, frictionless shields, and speed washers, so you have everything required for a full setup right out of the box.

You shouldn't need to lubricate them frequently. Because of the ceramic hybrid design and the protective diamond matrix coating, these bearings are designed to run efficiently for a long time. Apply a small drop only if you notice a decrease in performance or if they begin to sound dry after heavy use.

While they are optimized for park and transition skating, the durable construction makes them versatile enough for street use as well. The high-strength thermoplastic cage is designed to handle the impact and vibration common in street skating.
