CeramicSpeed 1/4" (6.350mm)

The CeramicSpeed balls undergo an extensive manufacturing process to ensure the highest possible material density, so you don't have to worry about their durability. Our "Hammer Test" video is an impressive proof of the quality and durability of the materials we use for our CeramicSpeed balls. We strive to source the highest quality rings for our bearings with specially polished surfaces to optimally combine them with our high-quality CeramicSpeed balls.

The unique manufacturing process takes 4–6 times longer than many of our competitors. This results in a ball that not only exceeds the standard specifications of "Grade 3" but also has a higher density and hardness down to the core. It is precisely this hardness of the ball that allows it to maintain the surface smoothness from manufacturing (measured at 0.08 micrometers or 0.00008 mm surface roughness).
