A hybrid bearing has ball material made of ceramic, silicon nitride (Si3N4) and 52100 bearing steel rings. This type of precision bearing is an excellent choice for advanced machines that require precision.

 

Ceramic balls offer numerous advantages over steel balls:

 

Ceramic is a lighter material than steel, so operating temperatures are reduced

Higher speeds can be achieved with the same size steel ball bearing

Contamination causes less damage to the bearing because of the hard ceramic material.
