Ceramic bearing assembly

Abstract

A ceramic bearing assembly includes an outer barrel having an inner wall formed with an axial receiving hole, an inner barrel rotatably mounted in the receiving hole of the outer barrel and having an inner wall formed with an axial shaft hole, a first retaining ring mounted in the receiving hole of the outer barrel and rested on a first side of the inner barrel, and a second retaining ring mounted in the receiving hole of the outer barrel and rested on a second side of the inner barrel. Thus, the outer barrel is rotated on the shaft smoothly and stably without producing deviation during rotation, thereby enhancing the lifetime of the ceramic bearing assembly.
