CeramicSpeed 1/4" (6.350 mm) replacement bearing balls
CeramicSpeed balls undergo an extensive manufacturing process to ensure the highest material density, so you don't have to worry about their lifespan. Our hammer test video is a great testament to the quality and durability of the materials we work with for our CeramicSpeed balls. We strive to source the highest quality bearings for our bearings with specially polished surfaces to best match our high-quality CeramicSpeed balls. The unique manufacturing process is 4-6 times longer than that of many of our competitors. The result is a ball that not only exceeds the standard 'Grade 3' specifications but also has higher density and hardness all the way to the center of the ball. It is this hardness of the ball that allows it to maintain its surface smoothness from manufacturing (measured at 0.08 microns or 0.00008 mm for surface measurement).
