Ceramic Ball Bearings Vs Stainless Steel

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

Ceramic ball bearings vs stainless steel. A ceramic bearing is also harder than steel bearings up to 30 which improves durability and they also don t rust so less maintenance should be required. This means lighter weight reels since the balls make up 50 75 of a bearings weight. Results 1 to 12 of 12 thread. If solid ceramic they re lighter than stainless steel by as much as 60.

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. 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. Cost of purchase for ceramic and steel bearings.

The wear rate of ceramic ball bearings is significantly less than stainless steel especially when lubricated. Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race. Geometrically the contact points inner and outer dimensions and thickness between steel and ceramic bearings is the same so they are interchangeable.

Frictional differences between a high quality steel ball and a ceramic is a 10 15 improvement at best. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. Can be solid or a coating on stainless steel balls. They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here.

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 first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic 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 only real big noticeable difference between the two is the bearing clearance.
