Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. The Boca Bearing Company's new line of ceramic hybrid machine tool bearings are designed for today's demanding environments. The latest bearing design delivers higher spindle speeds and increased stiffness. This allows the spindle to machine more material in less time while maintaining tolerances.
