Reduced weight Orion Spinner Fidget Silicon Nitride (Si3N4) is 58% lighter than steel, this reduces the load on the other components in the bearing, thereby increasing the maximum speed of the bearing by 30-50%. Reduce need for lubrication Orion Spinner Fidget Ceramic Speed Balls are 4 times smoother than steel. The friction coefficient of Ceramic Speed Balls against steel is 0.2, whereas the friction coefficient of steel against steel is 0.8. Low Friction Orion Spinner Fidget ceramic balls are rounder, lighter and smoother, reducing friction and energy loss in comparison to steel balls. Optimizing other components in the bearing reduces friction even further - without reducing the lifetime. Extreme wear resistance Orion Spinner Fidget Silicon Nitride balls are 2.3 times harder than hardened steel.
