Dimensions: Standard 608 size (8mm Bore, 22mm Outer Diameter, 7mm Width).
Capacités de charge: Dynamic Load Rating (Cr): 12 kN | Static Load Rating (Cor): 6.65 kN.
Speed: Engineered for high RPMs, allowing for incredible acceleration and sustained coasting speed that steel bearings cannot match.
Poids: Up to 30% lighter than all-steel bearings, reducing rotational mass for quicker wheel response and a more agile board feel.
Durability: The combination of materials makes these bearings virtually impervious to rust, corrosion, and wear from dirt and moisture. They perform consistently in wet or dry conditions.
Entretien: Requires less frequent cleaning and lubrication than standard bearings. The included high-speed lubricant is optimized for the ceramic-steel interface.
Dimensions: 8mm inner diameter × 22mm outer diameter × 7mm width
Ball Material: Silicon nitride (Si3N4) boules en céramique - plus léger, harder, and smoother than steel balls
Races & Rings: High-precision chrome steel (GCr15), précision?ground for consistent tolerances
Surface Finish: Black oxide coating - provides enhanced corrosion resistance and a distinctive professional appearance
Cage: High-strength nylon or steel retainer (depending on variant) for stable ball spacing and reduced friction
Shields: Double-sealed or removable rubber shields to block dust, debris, and moisture while allowing easy cleaning
Precision Rating: ABEC-7 / ABEC-9 / ABEC-11 grade options available for smooth rolling and consistent performance
