Ceramic Ball Bearings Vs Steel

Ceramic ball bearings vs steel.

Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race. Frictional differences between a high quality steel ball and a ceramic is a 10 15 improvement at best. They use ceramic balls and usually a steel inner and outer race. 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.

Stainless steel bearings win the prize for load and speed ratings. The hybrid comes from the races which remain of stainless steel. They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. Ceramic bearings are in actual fact hybrid.

Ceramic hybrid bearings use silicon nitride as it is the hardest and frequently used. The ceramic balls when manufactured by a top quality bearing manufacturer are rounder lighter and smoother than steel balls. The ceramic balls are often silicon nitride or equivalent. Cost of purchase for ceramic and steel bearings.

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. Of the different components of a bearing races cages seals grease friction from the actual ball bearings is only about 3. Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance. This means that the overall friction reduction between a high quality steel bearing and a ceramic is below 0 5.
