Does Ceramic Bearing Need Lubricant

We may need to rethink lubing ceramic bearings they may not need any lube not even a thin film of oil.

Does ceramic bearing need lubricant.

Mineral or synthetic based lubricants are the most commonly used and are designed for general and high speed use. Normally from the experience dealing with inter metal friction the light oil may not stay between two metal surface under a high load to decrease the friction. The grease in a bearing will help capture dirt and particulates and keep them away from rolling elements of the bearing. If you choose to run ceramic hybrid and full ceramic bearings wihtout grease then more frequent cleaning is recommended.

As my understanding ceramic bearing can work without grease but they should work better with appropriate lubrication. For ceramic hybrid and full ceramic bearings grease is recommended but not required. For minimum rolling resistance lighter weight greases are better. Grease and oil are common lubricants for hybrid bearings but ceramic bearings are less sensitive to fluctuations in lubrication conditions.

The rolling resistance of a ceramic bearing compared to an abec 3 5 or 7 steel ball bearing is offset by the resistance of the grease he says. All bearings whether steel or ceramic require lubrication. Ceramics have lower density thermal expansion and friction than. Lube helps prevent rust roll easier dissipate heat and makes steel bearings last longer.

The lubricant will affect maximum running speed and temperature torque level noise level and ultimately bearing life. None of these may apply to ceramic bearings. Do i have a carbon fiber bike. There is absolutely nothing magic about ceramic bearings including what lube you choose to use.

For example compared to steel bearings ceramic balls can operate under the same lubrication conditions at speeds up to 20 higher. Any grease will work just fine. We are so accustomed to lubing things lubrication everything we do we lube. Bicycles that have ceramic bearings need ceramic grease or ceramic safe grease to maximize performance as well as protect the bearings from unnecessary wear.

There are a range of options depending on the application. For riding in the rain fully waterproof greases are better stay away from lithium grease. Does this mean i should run my ceramic ball bearings dry or with light oil.
