Ceramic Bearings are lubricated with oil...they require more maintenance than standard steel bearings in many cases. cleaning, blowing out, and a drop or two of light bearing oil.
Standard steel bearings are most often packed with grease. This allows them to last quite awhile without maintenance, but adds a bit more resistance. If you blow them out and add oil instead, they will require maintenance more often.
