摘要： In order to ensure high levels of insulation performance, and low cost, and have an excellent external appearance, as a ceramic constituting an insulating coating 6 being a ceramic coating layer, one with alumina as its main component, and in which the content of titanium oxide is limited to 0.01 to 0.2 percent by weight is used. Moreover, a particle size of ceramic forming the coating layer is 10 to 50 μm, and average particle size is 15 to 25 μm. By limiting the content of titanium oxide, the insulating coating 6 can be made thin, and by limiting the particle size the film thickness accuracy can be improved, thus simplifying finishing. Moreover, by mixing of titanium oxide, deterioration of the external appearance after sealing can be prevented. As a result, the above problem is solved.

摘要： To provide a rolling bearing in which a spin slippage between a rolling element and a raceway groove is suppressed, and a rolling resistance is reduced to make the torque lower, whereby the rolling elements are easily incorporated even when the bearing rings are the monolithic type. Also, to provide the rolling bearing in which the rolling elements are easily incorporated even in a state where the bearing rings of monolithic type and a retainer are assembled. After the outer and inner races and the retainer are assembled, a small groove 4 for rotating the rolling element is provided in the center of an inner raceway groove 3 within a raceway groove space. The retainer 6 is only provided in one axial pocket face 7b of a pocket 7, and the other face is opened.
