Precision ceramic balls spin true and fast
The Boca Bearing Company now offers ceramic bearings for mountain, road, velodrome, and BMX bikes. The ceramic bearings are similar to the heat absorbing, super resilient tiles on the Space Shuttle.
The “full ceramics” bearings are not recommended for off road bikes but are more suited for controlled riding environments like road and velodrome racing. Full ceramics have been introduced as a further enhancement to take discerning riders further and with less effort.
Ceramic hybrids are also being introduced to provide more protection in abusive areas such as bottom brackets. Ceramic silicon nitride balls, for example, exhibit much greater hardness than steel balls resulting in at least ten times greater ball life due to its ability to hold the surface finish longer. The ball has dramatically smoother surface properties than the best steel ball resulting in less friction between the balls and bearing race surfaces. Thermal properties are also dramatically improved over steel balls resulting in less heat build . . . to read the rest of the story, click here.
