Ceramicspeed Ceramic Coated Bearing - 6903 Info
The CeramicSpeed Ceramic Coated Bearing - 6903 is a direct upgrade for riders who want measurably less resistance in their drivetrain or wheel hubs. Silicon nitride ceramic balls run against hardened steel raceways, and the coated version adds an additional layer to the raceway surface — further reducing friction and extending service life well beyond what a standard steel bearing delivers. CeramicSpeed rates these bearings at three to five times the longevity of industry-standard alternatives.
A reinforced polymer cage keeps the balls aligned and spaced consistently, while specialized seals are designed to keep dirt and moisture out without adding meaningful drag. The bearings are packed with CeramicSpeed's own grease formulation, matched to the materials and tolerances of the ceramic ball set. The result is a bearing that maintains its performance characteristics over a significantly longer service interval than conventional options.
CeramicSpeed Ceramic Coated Bearing - 6903 Specs at a Glance

- Cage material: Reinforced polymer
- Lubrication: CeramicSpeed proprietary grease
- Sealing: Sealed against dirt and moisture ingress
