Disclosed is a rolling bearing totaly made of ceramics. The bearing consists of an outer ring (1), an inner ring (2) and multiple balls (3a) or needles placed between the outer and inner rings (1,2), and the balls (3a) or needles are retained by a bracket (12) provided on the outer ring (1) or the inner ring (2) and a retaining ring (4a) which cooperate with the bracket. Fixing of the retaining ring (4a) is achieved by engagement of screws or adhesion. The ceramics bearing displays high durability as well as good heat-resistance and corrosion resistance.
