Full ceramic bearings do not require lubrication to run. Ceramic is non-porous and as a result, it is practically frictionless. Dry ceramic bearings are an option. Unlike stainless steel bearings, full ceramic bearings do not suffer heat build-up within the bearing and therefore do not need lubrication to help dissipate the heat although an effective lubricant can be used to support higher speeds.
Full ceramic bearings are the only type of bearing recommended to run dry at anything other than very low speeds. For other bearing materials, lubrication can be essential to the bearings operation.
