The Cema 6803LLB-2RS ABEC5 Ceramic Wheel Bearing is a replacement cartridge bearing designed for compatible bicycle wheel hubs. Combining silicon nitride ceramic balls with hardened steel races, it provides smooth rotational performance and durability. Its hybrid ceramic construction is intended for riders seeking efficient bearing operation in compatible wheel assemblies.

Hybrid Ceramic Construction: The ceramic balls are harder and lighter than conventional steel balls, helping reduce rolling resistance. Combined with precision-manufactured steel races, this construction supports consistent bearing rotation. The ABEC5 precision rating indicates controlled manufacturing tolerances for dependable performance.

Double-Sealed Protection: The bearing features seals on both sides to help retain lubrication and limit the entry of dirt and moisture. Its sealed cartridge construction protects the internal rolling elements during regular riding. Before installation, confirm that the bearing dimensions and sealing configuration match the original bearing fitted to the wheel hub.
