Ceramic Ball Bearings For Bicycles

Cutting to the chase on ceramic bearings on a bicycle.

Ceramic ball bearings for bicycles.

Ceramic which is significantly harder does not have this ability. The material can be polished smoother than any metal reducing friction and wear. Modern cartridge bearings come as a closed unit with balls and races packed in a single unit. Fitting ceramic bearings on your bike may be a bit like fitting a formula one gearbox in your ford fiesta and expecting it to perform as well after 100 000 miles.

The silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings. However many bicycles still use older cup and cone system where balls can and should be replaced with new ones when servicing bearings. Two types of ceramic materials there are two materials that are common for use on bikes. Bicycles usually use ball bearings.

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. This is the case with most shimano hubs wheels they still use the cup and cone system. This is different from a full ceramic bearing which would have both the balls and the races made of ceramics.

Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum. 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. This impact leaves a very small dent or pit in the steel race. 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.

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.
