Does ceramic bearing need lubriant.

There is absolutely nothing magic about ceramic bearings including what lube you choose to use. Ceramic grease represents finish line s most advanced bearing lubrication technology. We may need to rethink lubing ceramic bearings they may not need any lube not even a thin film of oil. The grease in a bearing will help capture dirt and particulates and keep them away from rolling elements of the bearing.

All bearings whether steel or ceramic require lubrication. Although most cyclists don t give much thought into what kind of bike bearing grease they need putting the wrong grease in the wrong spot can reduce performances and even cause. For riding in the rain fully waterproof greases are better stay away from lithium grease. But occasionally a dry bearing may be specified.

If you choose to run ceramic hybrid and full ceramic bearings wihtout grease then more frequent cleaning is recommended. Lube helps prevent rust roll easier dissipate heat and makes steel bearings last longer. None of these may apply to ceramic bearings. Ceramics have lower density thermal expansion and friction than.

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. Does this mean i should run my ceramic ball bearings dry or with light oil. Any grease will work just fine. For ceramic hybrid and full ceramic bearings grease is recommended but not required.

Oil lubrication allows for more efficient movement of the ball through the lubricant as compared to greases the difference between dry and lubricated bearings. For example compared to steel bearings ceramic balls can operate under the same lubrication conditions at speeds up to 20 higher.

If you don t want to read the full article below we consider white lightning crystal grease to be the best bike grease for bearings.

Grease and oil are common lubricants for hybrid bearings but ceramic bearings are less sensitive to fluctuations in lubrication conditions. In order for a ceramic ball bearing to out perform a steel ball bearing grease is not an option. Kelly explained that most bearings will require lubrication to some degree. Ceramic bearings do not undergo cold welding or corrode so they don t need oil or grease to extend operating life.
