A planetary gear assembly for a planetary gear system is provided to improve durability of the planetary gear system by preventing the planetary gear assembly from being partially contacted with a ring gear. A planetary gear assembly for a planetary gear system includes a gear shaft(22), a planetary gear(40), and a bearing(32). The gear shaft serves as a rotation center. The planetary gear is rotatably implemented on the gear shaft. The bearing is arranged between the planetary gear and the gear shaft and supports the planetary gear and the gear shaft, so that the planetary gear and the gear shaft are rotated with respect to each other. The gear shaft includes a center pin(24), a support pin(26), and a spacer pin(28). The support pin penetrates into the center pin and is coupled with one end of the center pin. The spacer pin penetrates the center pin and is coupled with the other end of the center pin. An end of the spacer pin is inserted into the support pin. The spacer pin is apart from an outer surface of the center pin and an inner surface of the support pin.
