Steel Bearings Vs Ceramic

On the one hand much of the cycling public associates bearing upgrades with going ceramic and on the other hand there is a healthy chunk of cyclists from all demographics who believe ceramic bearings are just marketing hype and a waste of money.

Steel bearings vs ceramic. 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. The ceramic balls are often silicon nitride or equivalent. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings.

Stainless steel bearings vs ceramic bearings stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance. They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here. It takes weeks for a kogel ball to sit in a tumbler and be perfectly polished. Balls ceramic vs steel balls are that part of the bearing that actually does the rolling.

They use ceramic balls and usually a steel inner and outer race. One can argue that they are the most important component of a bearing. Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed. This is mostly due to the additional time spent to perfect a quality ceramic ball.

Ceramic bearings exist to help manage heat in high rpm applications. They don t expand or deform when they contact each other hertzian stress as much as steel bearings when they get really hot. This debate has been going on since the great flood. This article to try to assist with this fun little area.

Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race. The ceramic balls when manufactured by a top quality bearing manufacturer are rounder lighter and smoother than steel balls. Hybrid ceramic vs steel bearings. While they use ceramic balls these bearings are paired with metal inner and outer rings.

While a formula 1 engine revving to 15 000 rpm can create a lot of heat that can deform and swell steel bearings. Ceramic bearings are in actual fact hybrid.
