という欠点があった。To measure the raceway groove pitch Pa of the double-row outer ring 8, while the side surface 11 of one side of the double-row outer ring is in contact with the reference surface 5 of the measuring device main body, a measuring section is placed on each raceway groove 9 and 10 surface of the double-row outer ring. 3 are brought into contact with each other, and the setting standard value (measured value when measuring the reference master) of the raceway groove position dimension of the double-row outer ring 8 at this time is measured at the measuring part 3. The amount of displacement is indicated by the indicator 7, and the positional dimensions A and B of each raceway groove are measured, and the difference between the measured positional dimensions A and B of each raceway groove is used to determine the raceway groove pitch Po'! However, the raceway groove pitch Po of the double-row outer ring measured in this way is determined by the relative movement of the outer ring and inner ring in the axial direction in a double-row Angiela ball bearing assembled using this double-row outer ring. When this is done, there is a substantial difference from the raceway groove pitch at the position where the rolling elements contact the raceway groove surface of the double-row outer ring. In general, the axial clearance in a double-row angular contact ball bearing is determined by a combination of various factors ζ, including the raceway groove pitch of the bearing ring, raceway diameter and raceway groove radius, and machining dimensional errors such as ball diameter. Therefore, in order to obtain a predetermined axial clearance for the double-row Angiela Tamashima bearing, when assembling the bearing into a string bearing, there is a drawback that the selection and combination of the bearing components, which are the outer ring, inner ring, and balls, is complicated, and the work efficiency is reduced. There is a problem in improving the performance of the bearing, and the raceway groove pitch of the conventional raceway ring has the drawback that it is inappropriate as a representative characteristic value when assembling the bearing.
