ABSTRACT:
The invention provides a special type bearing device that is insusceptible to damage, is light in weight, has a long service life and excellent wear resistance, is insusceptible to the effect of change in temperature, is easy to fabricate, and has little offensiveness towards mating members. Further, the same is capable of sufficiently retaining a lubricant such as oil and grease, and retaining the lubricant for a long period of time without the need of supplying oil during operation, thereby rendering it maintenance-free. That is, the special type bearing device as described above has an axial shaft, a pair of rotating bodies fixedly attached to the shaft, and a supporting body with which the rotating bodies are in contact, wherein any one of the shift, the rotating bodies, and the supporting body is made of RB ceramic or CRB ceramic.
