Hybrid Ceramic Bearings

I. Components of a hybrid bearing
1) Steel races
Chrome steel/Stainless steel
2) Ceramic balls Si3N4/SiC/ZrO2/Al2O3
3) Ball Cage/Retainer
Steel/Nylon/PEEK/Teflon
4) Seals/Shields
Rubber/Steel/PEEK/Teflon
5) Lubricant Dry/Oil/Grease

II. Features and benefits of hybrid ceramic bearings

Features	Benefits
Higher hardness of rolling element	- Better wearability - Greater durability - Longer service life
Lower gravity	- Lightweighting the system - Lower centrifugal force during rotation, consequently less bearing wear and heat generation and bearings can run at higher speed
Higher stiffness	- Increase the rigidity of system - Less sphere deformation under load and this will transfer energy better
Higher precision and better surface finish of ceramic balls	- Less friction between ceramic balls and races - Less wear
Good corrosion resistance	- Less maintenance or maintenance free - Races will not block due to rusty
Self-lubrication	- Suitable for dry run
Magnetism free	- Less magnetic contaminations to be magnetized into the raceway that can affect smooth rotation and destroy the raceway
Electrical isolation	- No galvanically stimulated corrosion - Can be used in applcation that requires electrical isolation
