All CeramicSpeed Bearings are hand-built in Denmark.
Super smooth CeramicSpeed grade 3 Silicon Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove.
The balls are held in place by a reinforced polyamide cage.
Every bearing is optimised with a low viscosity CeramicSpeed “Blue Grease” to minimise fiction and increase bearing life.
Non-contact seals complete the bearings, keeping dirt and moisture out.
