Ceramic Ball Bearings Vs Steel

The ceramic balls when manufactured by a top quality bearing manufacturer are rounder lighter and smoother than steel balls.

Ceramic ball bearings vs steel.

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

Silicon nitride zirconium dioxide and silicon carbide are the materials used in the manufacture of ceramic ball bearings. They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. This reduces friction by up to 40 as well as energy loss allowing your equipment to run more efficiently with ceramic ball 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. Frictional differences between a high quality steel ball and a ceramic is a 10 15 improvement at best. Ceramic hybrid bearings use silicon nitride as it is the hardest and frequently used. The hybrid comes from the races which remain of stainless steel.

Ceramic bearings are in actual fact hybrid. They use ceramic balls and usually a steel inner and outer race. Ceramic bearings vs steel bearings advanced ceramic manufacturer. This means that the overall friction reduction between a high quality steel bearing and a ceramic is below 0 5.
