AHZ Ceramic 13x20x4mm Rubber Sealed Wheel Bearings (2)

This is a NEW set of bearings from Absolute Hobbyz. These bearings are Rubber Shield Ceramic Bearings, size is 13x20x4mm. Two pieces are included in the package.

These are direct replacement bearings for the Team Xray XB808 series of cars. Please verify in the user manual that your specific cars uses this size of bearings.

Why Should You Use Ceramic Bearings:
Our ceramic bearings are designed with inner and outer chrome steel races with high precission ceramic balls. Ceramic bearings are lighter weight than its equal in steel. Ceramic bearings also have more resistance to wear and corrosion (rust). Ceramic balls are more true in design with allows for less vibration, and ceramic on steel has less friction.

Facts Of Ceramic Bearings:

• Resistance To Wear: Ceramic balls due to their extreme hardness and percission have a much longer resistance to wear.
• Lubrication: The design of ceramic bearings will allow them to perform with high performance under low or no lubrication. It is still recommended to use a light oil on these bearings.
• Weight: Ceramic balls are 50-60% lighter than steel, whic dramically decreases the centrifugal rotating force.
• Life: The life of a ceramic bearing under the same conditions as a steel bearing is 3-5 times as long.
• Friction Value: Ceramic balls have a much lower friction resistance than steel. The surface of ceramic balls is much smoother.

Best Performace Practice:

With ceramic bearings, it is a good practice shim correctly and not tighten too much, and that you keep a well lubricated bearing.
