Ceramic Ball Bearings Vs Steel

Stainless steel bearings win the prize for load and speed ratings.

Ceramic ball bearings vs steel.

The ceramic balls are often silicon nitride or equivalent. 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. 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.

Silicon nitride zirconium dioxide and silicon carbide are the materials used in the manufacture of ceramic ball bearings. Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race. The ceramic balls when manufactured by a top quality bearing manufacturer are rounder lighter and smoother than steel balls. They use ceramic balls and usually a steel inner and outer race.

They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. Ceramic bearings are in actual fact hybrid. Frictional differences between a high quality steel ball and a ceramic is a 10 15 improvement at best. Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.

The hybrid comes from the races which remain of stainless steel. Ceramic bearings vs steel bearings advanced ceramic manufacturer. 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 and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.
