PURPOSE:To obtain self-aligning function so as to be adapted to rapid change of temperature by making spherical surfaces of intermediate spacers and tightening spacers be those with the center of a rolling bearing as the core of a sphere. CONSTITUTION:Both flat surfaces 11 of an inner race 1 are out-open tapered surfaces with respect to the center O of a bearing. Also, a pair of intermediate spacers 5 with tapered surfaces 51 facing the tapered surfaces 11 of the inner race 1 are formed in convex spherical shape at their respective other side surfaces 52, and their cores of the spheres almost coincide with the center O of the bearing. And, a pair of tightening spacers 6 with concave spherical surfaces 61 facing the convex spherical surfaces 52 are made of material having the almost equal coefficient of linear expansion to that of an axis 7, so as to provide for interference fit to the axis 7. |
