Precision made, Hot Isostatic Pressure Sintered (HIPS) Silicon Nitride ceramic balls are super-fast, smooth rolling, and durable for extended use.

Balls roll deep in raceway channels – reduces side impact damage amp; breakage.Pop off resistant – hold oil in, dirt and moisture out – easy to clean.

Non-distortion custom cage keeps the balls precision spaced amp; oil circulating.Linear micro-groove surfaces improve bearing lubrication, speed and spin.Nano-ceramic compound for wear protection – moisture, rust, amp; corrosion resistant.

Eliminates shield and cage contact on impact for a go fast, stay fast bearing.Nitrogen filled shrink wrap, reduces metal amp; oil oxidation until ready to be ridden.Case doubles as a bearing cleaning unit by following the included instruction sheet. (Also sold separately)
