Does Ceramic Bearing Need Lubricant

Bicycles that have ceramic bearings need ceramic grease or ceramic safe grease to maximize performance as well as protect the bearings from unnecessary wear.

Does ceramic bearing need lubricant.

Lube helps prevent rust roll easier dissipate heat and makes steel bearings last longer. Petroleum or ptfe teflon based bicycle greases can cause damage to carbon fiber bicycles so make sure you have a carbon safe grease on hand. Do i have a carbon fiber bike. 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.

The lubricant will affect maximum running speed and temperature torque level noise level and ultimately bearing life. For minimum rolling resistance lighter weight greases are better. None of these may apply to ceramic bearings. If you choose to run ceramic hybrid and full ceramic bearings wihtout grease then more frequent cleaning is recommended.

Ceramic bearings do not undergo cold welding or corrode so they don t need oil or grease to extend operating life. There is absolutely nothing magic about ceramic bearings including what lube you choose to use. We are so accustomed to lubing things lubrication everything we do we lube. For riding in the rain fully waterproof greases are better stay away from lithium grease.

Any grease will work just fine. All bearings whether steel or ceramic require lubrication. 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. As my understanding ceramic bearing can work without grease but they should work better with appropriate lubrication.

In order for a ceramic ball bearing to out perform a steel ball bearing grease is not an option. The grease in a bearing will help capture dirt and particulates and keep them away from rolling elements of the bearing. There are a range of options depending on the application. For example compared to steel bearings ceramic balls can operate under the same lubrication conditions at speeds up to 20 higher.

Does this mean i should run my ceramic ball bearings dry or with light oil. We may need to rethink lubing ceramic bearings they may not need any lube not even a thin film of oil. Ceramics have lower density thermal expansion and friction than.
