Crafting the fastest bearing products for cycling and industry since 2004.
Ceramic bearings for bicycle.
The silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings.
With the exception of one product the entire line of kogel bearings runs on hybrid ceramic bearings.
They ceramic bearings do run with less friction which offers a significant advantage in industrial applications running at 20 000 rpm.
Miniature full ceramic and ceramic hybrid bearings are particularly well suited to both competitive and recreational bicycle applications.
Hand built in denmark.
However the reality of why some bearing designs are faster than others doesn t always align with what is presented.
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.
The influx of ceramic bearing development into the bike industry sparked needed focus on reducing rolling friction in bearings.

This is different from a full ceramic bearing which.

The material can be polished smoother than any metal reducing friction and wear.
Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum.
Full ceramic bearings for bicycles.
Hybrid means that the balls are made of a ceramic material but the races or rings are made of a hardened steel.
Ceramic bearings are fitted to.
The boca bearing company have been an industry leader in ceramic bearing technology since 1987.
Ceramic bearings are often represented as the ultimate way to minimize rolling friction on your bike.
Every single bearing is hand built in denmark under laminar flow clean room conditions.
A ceramic hybrid bearing has steel races with ceramic balls and a full ceramic bearing has ceramic races and balls.
