Ceramic ball bearings vs steel turbo.
A top class set of steel bearings as compared to a much promoted ceramic bearing is just as high performing.
Ceramic bearings are able to fulfil these requirements as many of them are lightweight and vacuum compatible.
The biggest price paid on ball bearing turbos is continuous motion and pressure.
Ceramic bearings in my opinion are just not worth it.
They also have a much higher operating temperature range than stainless which will anneal soften at a much lower temperature.
Ceramic balls are less prone to expansion than steel balls which means bearings with ceramic balls will be more precise than steel bearings and produce less vibration.
Ceramic is brittle and unlike steel does not handle vertical loading well.
Https bit ly 2kabytm in this video i m showing the main difference between standard steel ball bear.
This video will show you how efficient the ceramic ballbearing is.
Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.
Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race.
This load on the ball bearings causes them to rut their housing.
Ceramic bearings are more dimensionally stable at high temperature than stainless 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.
Electrically non conductive if you have an electric motor that is controlled by a variable frequency drive it is important that you use an electrically non conductive bearing.
The ceramic balls are often silicon nitride or equivalent.
In the racing world with leaded fuels ceramic bearings will get contaminated with the lead in the fuel and these deposits also cause premature failures.
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.
Thus causing failure to the unit.
There are many other differences but for turbo applications that is the main draw.
They use ceramic balls and usually a steel inner and outer race.
Unlike their steel equivalents ceramic bearings are able to run unlubricated which not only stops possible contamination of delicate components in the surrounding applications but also reduces weight as there is no need for heavy greases.
