Ceramic bearings vs steel bearings bicycle wheels.

Geometrically the contact points inner and outer dimensions and thickness between steel and ceramic bearings is the same so they are interchangeable. The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings. Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race. How to get the best performance from ceramic bearings ceramic speed.

Because ceramic bearings are rounder with a smoother surface and more uniform size friction is reduced and that can contribute to a less energy required to turn the cranks or spin the wheels. 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. They ceramic bearings do run with less friction which offers a significant advantage in industrial applications running at 20 000 rpm. Because ceramic races are more brittle than steel.

Steel rings and ceramic balls are the gold standard for bicycle wheel bearings. The advantages of steel are not the only argument against ceramic bearings. A tiny percentage reduction in friction here can equate to a worthwhile power saving but when you re only turning at 300 rpm as you do on a bicycle a small percentage increase in efficiency will make a negligible change to your power output. How to get the best performance from ceramic bearings ceramic speed.

Cracking a race could stop a wheel from turning instantly and no good comes of wheels permanently locking up on a bicycle. More durable than high quality steel bearings. You choose your adventure we build the bearings to match. Cost of purchase for ceramic and steel bearings.

This is mostly due to the additional time spent to perfect a quality ceramic ball. Quite a few wheel manufacturers state that the use of aftermarket bearings in their wheels voids the warranty.
