Provided they re of the highest quality like cerbec balls.
Cerbec ceramic ball bearings.
Ceramic balls have considerably lower amount of thermal expansion compared to steel balls.
Coorstek can engineer precision cerbec balls for size.
We improve them by superfinishing the steel races then coat the races and the ceramic balls with microblue the only coating that changes the way lubricants work.
This is why ceramic bearings spin so much smoother and quieter therefore more efficient than steel balls.
Silicon nitride is non porous non magnetic non corrosive lighter than steel and in ball form is harder than steel.

Cerbec bearing components use proprietary coorstek silicon nitride compounds delivering the ultimate combination of durable mechanical strength thermal stability corrosion resistance dielectric properties and value for hybrid and all ceramic bearings.
Coated ceramic ball bearings.
Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.
Why are ceramic bearings better.
Because ceramic balls are non porous they are virtually frictionless and are capable of spinning faster than steel balls.
