CERAMIC ROLLING BODY, MANUFACTURING METHOD THEREOF, AND ROLLING BEARING
PROBLEM TO BE SOLVED: To provide a silicon nitride ceramic rolling body enabling mutual recognition under visible light or ultraviolet light.SOLUTION: A ball, cylindrical roller, needle roller, spherical roller or conical roller ceramics rolling body comprises a ceramics compact, and is arranged on an annular raceway of a rolling bearing. The ceramics compact has a mirror surface polishing surface, and has, on the mirror surface polishing surface, a phase of a sintered body A, and a phase of sintered body B arranged so that a pattern of the phase can be discriminated from the phase of the sintered body A under visible light or ultraviolet light.SELECTED DRAWING: Figure 1
【課題】可視光下または紫外光で相互に認識できる窒化ケイ素セラミックス転動体を提供する。【解決手段】セラミックスの成形体からなり、転がり軸受の円環状の軌道上に配置される、玉、円筒ころ、針状ころ、球面ころ、または円錐ころセラミックス転動体であって、セラミックスの成形体は、鏡面研磨表面を有し、焼結体Ａの相と、この焼結体Ａの相に対して可視光または紫外光照射下において相の模様が識別可能に配置された焼結体Ｂの相とを鏡面研磨表面に有する。【選択図】図１
