Dimensions: Standard 608 size (8mm Bore, 22mm Outer Diameter, 7mm Width).
Load Ratings: 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.
Weight: 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.
Maintenance: Requires less frequent cleaning and lubrication than standard bearings. The included high-speed lubricant is optimized for the ceramic-steel interface.
Compact one-way clutch bearing with high torque capacity (≥6 N·m). Allows free rotation in one direction while instantly locking in the opposite direction. Ideal for fishing reels, anti-reverse mechanisms, overrunning clutches, indexing systems, and compact motion control applications.
