Ceramic Ball Bearings Cycling

At kogel bearings we believe ceramic bearings set the gold standard for your bicycle bottom bracket derailleur pulleys and wheel bearings.

Ceramic ball bearings cycling.

While full ceramic bearings ceramic races do exist they are reserved for low impact areas like derailleur pulleys. The silicon nitride used to make ceramic bearings combines a set of material properties that makes it perfect for bicycle bearings. Over time these pits lead to a rough noisy pedal stroke. 17x30x7mm ceramic ball bearing size 6903 ball bearing.

This 17x30mm bearing is a super high performance ceramic bearing which can be used for many high performance applications including bicycles this is a direct performance upgrade for a fulcrum r4 004 bearing and as a direct performance upgrade and replacement for the hpi baja. Full ceramic bearings for bicycles. With the exception of one product the entire line of kogel bearings runs on hybrid ceramic bearings. Loose ball loose ball in a retainer needle and cartridge are the main styles of bearing founds in cycling frames and components.

You can find cheaper examples but cheaper types offer minimal. Hand built in denmark. A ball and retainer system is similar to a loose ball setup but. 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.

This impact leaves a very small dent or pit in the steel race. Ceramic bearings are not cheap. A full set of cyclingceramic bearings starts at 80 and ceramicspeed wheel bearings cost from 240. Made from our world champion ceramic nitride pro series bearing material.

The silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings. Crafting the fastest bearing products for cycling and industry since 2004. Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum. The material can be polished smoother than any metal reducing friction and wear.

It s clear that alan and paul agree that the factors that make a ceramic bearing well suited to industrial and medical equipment applications and high altitude operating drone motors paul does a lot of work designing drones where the rpm is high the load is low and the operating conditions are clean are factors that mean they re not suited to cycling. The material is hard resistant to wear can be made into perfectly round balls with super tight tolerances and can be polished smoother than any metal.
