Provided they re of the highest quality like cerbec balls.
Cerbec ceramic ball bearings.
This is why ceramic bearings spin so much smoother and quieter therefore more efficient than steel balls.
8mm od 22mm width 7mm our price.
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.

Ceramic bearings used in racing are constructed using conventional hardened steel races but the steel balls replaced with cerbec ceramic balls made by saint gobain.
Coated ceramic ball bearings.
Why are ceramic bearings better.

These size 6902 super high performance ball bearings are from world champion acer racing s ceramic nitride pro series collection.
Ceramic balls have considerably lower amount of thermal expansion compared to steel balls.
Because ceramic balls are non porous they are virtually frictionless and are capable of spinning faster than steel balls.
Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
Silicon nitride is non porous non magnetic non corrosive lighter than steel and in ball form is harder than steel.
Long life and the need for minimal lubrication make this material appropriate for extreme applications.

Steel balls typically have tolerance variations between 50 and 60 millionths of an inch whereas a grade 5 cerbec ball will only have 10 millionths variation and have are a surface finish superior to steel balls.
Cerbec silicon nitride balls outperform traditional all steel bearing balls due to the tailored material properties and finishing that maximize the benefits of using ceramics making cerbec balls valuable in applications where steel balls degrade rapidly or where electrical insulation is a necessity.
