Full Ceramic Bearing Details
HSC's line of full ceramic cartridge bearings represent the leading edge of bearing technology in the cycling industry. One step ahead of the traditional hybrid ceramic which uses hardened steel races, these full ceramic bearings incorporate ABEC 5 Zirconia inner and outer races. The balls are manufactured from Silicon Nitride to a sphericity of grade 3, the highest standard available for cyclists. There is absolutely no steel on the bearing contact surfaces, so both balls and races are of similar hardness and will not push into each other. These cartridges are prepacked with a light, high-quality grease and fitted with dual lip labyrinth seals to ensure the highest, longest-lasting performance possible.
We recommend installation be performed by an experienced mechanic with a professional quality bearing press. Improper installation will negate the performance advantages of ceramic bearings, and significantly reduce their wear life.
