Ceramic Bike Bearings

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

Ceramic bike bearings.

Miniature full ceramic and ceramic hybrid bearings are particularly well suited to both competitive and recreational bicycle applications. The boca bearing company have been an industry leader in ceramic bearing technology since 1987. Crafting the fastest bearing products for cycling and industry since 2004. Our 6806 ceramic bearing can help bike racers and enthusiasts alike obtain the highest level of performance thanks to our skillful and innovative design and because the right kind of ceramic bearing brings major benefits in terms of durability friction and heat resistance as well as a tremendous decrease in rotational mass meaning less pedal.

Two types of ceramic materials. Silicon nitride a dark grey material and zirconium a bone colored material. Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum. This is different from a full ceramic bearing which would have both the balls and the races made of ceramics.

The material can be polished smoother than any metal reducing friction and wear. Should you be following in the footsteps of the pro racers then and upgrading your bike with ceramic bearings. This impact leaves a very small dent or pit in the steel race. 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.

There are two materials that are common for use on bikes. Ceramic which is significantly harder does not have this ability. A ceramic hybrid bearing has steel races with ceramic balls and a full ceramic bearing has ceramic races and balls. Every single bearing is hand built in denmark under laminar flow clean room conditions.

Hand built in denmark. 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.
