Cema 689DD Ceramic Bearing

The Cema 689DD Ceramic Bearing is designed to provide cyclists with exceptional performance and durability. With a hybrid ceramic construction and non-contact double-sealed design, these bearings offer a superior combination of precision, smoothness, and protection for your bike’s components.

Hybrid Ceramic Construction: This bearing features a hybrid ceramic design, combining ceramic balls with steel races. The ceramic balls reduce friction and enhance smoothness, providing a faster and more efficient ride. The durable steel races ensure long-lasting performance and resistance to wear, making these bearings perfect for demanding cycling conditions.

Non-Contact Double-Sealed Design: The non-contact, double-sealed closure system ensures that the bearings are well-protected from dirt, moisture, and other contaminants, all while maintaining low friction. This design promotes a smooth operation, allowing the bearings to function efficiently while staying clean and protected over time.

Cartridge Bearing for Smooth Operation: The Cema 689DD Ceramic Bearing features a cartridge design, ensuring that the bearing remains securely in place and operates with precision. This setup minimizes friction and allows for efficient, smooth wheel rotation, enhancing your overall cycling experience.

With its hybrid ceramic construction, double-sealed protection, and precise cartridge design, these bearings are built to enhance both speed and durability across a variety of riding conditions.
