What is better ceramic or steel bearings?
A ceramic ball 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. Most sealed ceramic bearings are actually hybrid ceramic bearings, which combine a steel race with ceramic ball bearings.

Why are ceramic bearings so good?
They are more corrosion-resistant, harder, and last longer in everyday use. 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. Ceramic deals with heat better, so less friction is a bonus.

Why are ceramic bearings expensive?
This is mostly due to the additional time spent to perfect a quality ceramic ball. It takes weeks for a Kogel ball to sit in a tumbler and be perfectly polished.

Do ceramic bearings need grease?
No, full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless.

How much faster are ceramic bearings?
He says ceramic bearings are said to be three to five times harder than steel bearings and, as a result, can withstand the force applied to them through chain tension and pedalling for longer. "The ceramic balls also insulate the steel races," says Sollenberger.

Are ceramic bearings loud?
Ceramic bearings are definitely louder than stock SS bearings.

Are ceramic ball bearings magnetic?
All-ceramic bearings are fully nonmagnetic. They also offer excellent resistance to corrosion and wear.

What is hybrid bearing?
Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4), which make the bearings electrically insulating. Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance, even under difficult operating conditions.

What's the application of ceramic bearings?
Ceramic bearings can be used for skateboard, bike, motorcycle, bicycle, fishing reels, ceramic bottom bracket and so on.
