Ceramic Vs Steel Bearings Hubs

Ceramic bearings vs steel.

Ceramic vs steel bearings hubs.

Supercharge your hub bearings for race day video the bearing diameters loose ball bearing systems require a measurement of ball diameter which is something like 3 16in 4 7625 mm. 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. I decided to test the capabilities of ceramicspeed enduro a cheap ebay bear. Ceramic deals with heat better so.

Ceramic bearings are often represented as the ultimate way to minimize rolling friction on your bike. The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings. While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4. The material can be polished smoother than any metal reducing friction and wear.

Ceramic bearings versus steel bearings the debate has gone on for a long time. Rolling resistance is the key trump card promoted by ceramic bearing fans. Initially the enduro bearing has lower friction at around 600km of use the ceramic bearing has worn a track into the comparatively soft steel races and the bearing friction starts to increase dramatically. The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.

Cost of purchase for ceramic and steel bearings. Optimization is possible for the disparity that exists between these parts. Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed. The different elements balls retainers and closures can change a bit.

This is mostly due to the additional time spent to perfect a quality ceramic ball. Steel bearings the silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings. The influx of ceramic bearing development into the bike industry sparked needed focus on reducing rolling friction in bearings. However the reality of why some bearing designs are faster than others doesn t always align with what is presented.

In our higher end cult bearings ceramic balls and races lighter lubrication is needed so they roll much quicker with less drag than standard steel bearings.
