Key Advantages of OAKEN Black Oxide Ceramic Bearings

1. Enhanced Pedaling Efficiency and Smoothness

Ceramic Ball Technology: Featuring G5-grade ceramic balls with an ultra-smooth surface and high hardness, these bearings minimize internal friction, making pedaling more efficient.
Black Oxide Coating: The oxide layer improves oil adhesion, reduces wear, and enhances operational efficiency.

2. Prolonged Lifespan

Outdoor cycling exposes bearings to water, mud, and chemicals. The black oxide coating forms a stable anti-corrosion layer, protecting bearings from harsh environmental factors and significantly extending their lifespan.

3. Versatile Performance Across Applications

Whether tackling high-load mountain biking or low-load, high-speed road cycling, black oxide ceramic bearings ensure stable performance, minimizing sliding and friction to deliver smooth rolling.

The Ideal Choice for Wheel Hubs and Bottom Bracket Bearings

Wheel Hub Bearings: High-performance wheel hub bearings must withstand heavy loads and long distances. Black oxide ceramic bearings reduce rolling resistance, boosting overall cycling speed.
Bottom Bracket Bearings: As the drivetrain's core, bottom bracket bearings require durability and efficiency. The black oxide layer enhances rust resistance, ensuring smoother pedaling and a longer lifespan.
