Loose Ball Bearings - Grade 5 Silicon Nitride - 1/8'' (3,175 mm) (50 pcs)

BKC-0023 - 1/8 (0.125) Grade 5 Si3N4 Ceramic Balls (50 pieces)

Upgrade your bicycle's rolling components with these high-performance Enduro Ceramic Balls. Crafted from pure Silicon Nitride (Si3N4) with an exceptional high density of 3.25 g/cm³ achieved through uniform compaction, these Grade 5 precision ceramic balls are designed for optimal durability and performance. Sourced from Japan, they feature a near-perfect sphericity with a deviation of just 5/1,000,000. Being 60% lighter and seven times harder than steel, they significantly reduce friction for smoother operation. More resilient and less brittle than other ceramic options, Enduro Si3N4 balls offer superior corrosion resistance and are unaffected by magnetic interference, making them ideal for high-end cycling applications.
