摘要： PROBLEM TO BE SOLVED: To easily and precisely assemble a rolling body and a separator to a bearing body by inserting the rolling body and the separator while adding a returning force to the rolling body and the separator from the direction opposite to the insert port. SOLUTION: When a steel ball 9 is integrated to each circulating passage through an integration port 15a, the height of the steel ball line present on the integration port 15a side reaches about the integration port 15a. At this time, a downward load is added by the dead weight of the steel ball line located on a discharge port 15b side to generate a returning force of the direction opposite to the integrating direction of the steel balls in the integration port-side steel ball line through the steel balls 9 in a U-shaped groove 21. Thereafter, a separator 11 and the steel ball 9 are alternately integrated through the integration port 15a so that the recessed side surface of the separator 11 makes contact with the steel ball 9, and the insertion is continued until the separator 11 is discharged from the discharge port 15b. After the steel balls 9 and the separators 11 are integrated into a bearing body in this way, a temporary shaft is pulled out, and the bearing body is mounted on a rail.
