Ceramic Hybrid 

Ceramic Hybrids last up to 10xs longer than Chrome Steel bearings.  These are used in applications where high speed, load and temperature are a factor. Ceramic balls are harder and rounder than stainless & chrome steel, so therefore they offer less rolling resistance. 

 *Nylon retainers handle up to 60% more speed than a standard steel retainer
