PROBLEM TO BE SOLVED: To significantly reduce a cycle time of a post-process after a stock discharging process compared with a cycle time of a process before the stock discharging process while suppressing cost rise of manufacturing facilities, and consequently, that of a ball bearing. SOLUTION: A stocker 13a capable of storing and discharging a plurality of intermediate assemblies is arranged between an assembly device 14, which manufactures the intermediate assembly being a ball bearing before mounting a seal ring, and a grease sealing device 15 for sealing grease in the intermediate assembly, in the flow direction of a workpiece. By this constitution, it is possible to prevent the post-process after the stock discharging process from being excessively divided into a plurality of processes by a work unit. Consequently, the cycle time of the post-process after the stock discharging process can be significantly reduced compared with the cycle time of the process before the stock discharging process.
