Ceramic Bearings Vs Steel

Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race.

Ceramic bearings vs 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. Five different parts go into building skateboard bearings and longboard bearings. Ceramic bearings exist to help manage heat in high rpm applications. The different elements balls retainers and closures can change a bit.

They don t expand or deform when they contact each other hertzian stress as much as steel bearings when they get really hot. It takes weeks for a kogel ball to sit in a tumbler and be perfectly polished. The ceramic balls are often silicon nitride or equivalent. The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings.

The concept behind a bearing is simple. Optimization is possible for the disparity that exists between these parts. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. While a formula 1 engine revving to 15 000 rpm can create a lot of heat that can deform and swell 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. Things don t slide or roll. Ceramic bearings vs steel.
