Ceramic Vs Steel Bearings

Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.

Ceramic vs steel bearings.

This means lighter weight reels since the balls make up 50 75 of a bearings weight. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. The different elements balls retainers and closures can change a bit. The concept behind a bearing is simple.

Optimization is possible for the disparity that exists between these parts. Stainless steel bearings win the prize for load and speed ratings. Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.

They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. Cost of purchase for ceramic and steel bearings. The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro. 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. The wear rate of ceramic ball bearings is significantly less than stainless steel especially when lubricated. Things don t slide or roll. July 19 2016 1 11am 1.

Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Can be solid or a coating on stainless steel balls. I know that there has been a debate between steel and ceramic bearings for a while but i have wondered how it effects the esk8 world as well. This is mostly due to the additional time spent to perfect a quality ceramic ball.

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.
