Ceramic Vs Steel Bearings Bike

This impact leaves a very small dent or pit in the steel race.

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. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed. This is mostly due to the additional time spent to perfect a quality ceramic ball.

The folks at enduro bearings argue that for bicycles the materials are far more important than abec ratings and that for most applications abec 3 and 5 are appropriate for all things bicycle. 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. Cost of purchase for ceramic and steel bearings.

Ceramic deals with heat better so. The material can be polished smoother than any metal reducing friction and wear. The ceramic balls are often silicon nitride or equivalent. Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race.

Steel bearings the silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings. 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.
