What is a Hybrid Skate bearing?

Our patented hybrid skate bearing design combines one Silicon Nitride black ceramic ball with six steel bearings. Using less than a complete set of ceramic balls offers many of the same benefits of a full ceramic, but at a lower cost. The single Silicon Nitride ball (one of the hardest materials on earth), helps to lower the friction of the bearing as a whole, and requires less lubrication than a full steel set. As with full ceramic bearings, the density of the the single ceramic ball creates a "grindstone" effect inside the bearing race, buffing out imperfections and effectively creating a "self healing effect".  Patent #US 20060182376 A1
