Switchable ceramic bearing

The utility model provides a switchable ceramic bearing. The ceramic bearing comprises an embedded outer ring, outer embedded teeth, embedded pits, cylindrical rollers, an inner ring and a roller path, wherein the embedded pits are formed in the side, deviating from the circle center, of the embedded outer ring at preset intervals, and the embedded pits form the outer embedded teeth; an outer sideroller path is arranged on the circle center side of the outer ring, an inner side roller path is arranged on the side, deviating from the circle center, of the inner ring, and the cylindrical rollers are arranged between the outer side roller path and the inner side roller path. The bearing is reasonable in structural design, compact in layout and reliable in performance, all parts are coordinated uniformly and organically form a whole, the bearing can be applied to various complex environments in the aerospace field, and the bearing is efficiently, easily and conveniently matched with a rotating shaft. 本实用新型提供一种可切换
