Ceramic Vs Steel Bearings Bike

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.

Ceramic vs steel bearings bike.

Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. In our higher end cult bearings ceramic balls and races lighter lubrication is needed so they roll much quicker with less drag than standard steel bearings. Steel bearings the silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings. This is mostly due to the additional time spent to perfect a quality ceramic ball.

This impact leaves a very small dent or pit in the steel race. 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 material can be polished smoother than any metal reducing friction and wear. On a bicycle which is considered a low speed application compared to a formula 1 car or motorcycle engine for example the ball bearing material itself steel or ceramic has little to no effect on the friction of the bearing assembly.

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. Cost of purchase for ceramic and steel bearings. When a bike with ceramic bearings goes over a bump the ball bearing which is harder than the steel race that contains it strikes the inner surface of the race.

Cutting to the chase on ceramic bearings on a bicycle. The ceramic balls are often silicon nitride or equivalent.
