Ceramic Ball Bearings Vs Steel

The hybrid comes from the races which remain of stainless steel.

Ceramic ball bearings vs steel.

They use ceramic balls and usually a steel inner and outer race. Ceramic hybrid bearings use silicon nitride as it is the hardest and frequently used. Once you have a considerable amount of mileage on a bearing set it is safe to think that the high quality bearing runs close to how you bought it and a basic bearing is closer to the end of it s life span. Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.

With a high quality ceramic probably lasting longer than a basic steel one think of how often you enter a major race or gran fondo with brand new bearings. Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed. The ceramic balls are often silicon nitride or equivalent. Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race.

Cost of purchase for ceramic and steel bearings. This reduces friction by up to 40 as well as energy loss allowing your equipment to run more efficiently with ceramic ball bearings. This means that the overall friction reduction between a high quality steel bearing and a ceramic is below 0 5. Stainless steel bearings win the prize for load and speed ratings.

Frictional differences between a high quality steel ball and a ceramic is a 10 15 improvement at best. Ceramic bearings are in actual fact hybrid. They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. Of the different components of a bearing races cages seals grease friction from the actual ball bearings is only about 3.
