The invention relates to a conveying chain and in particular relates to a lasting lubricating conveying chain. The conveying chain comprises inner chains plate, outer chain plates, a pin shaft and a roller; the outer chain plates are arranged on the outer sides of the inner chain plates the roller is arranged between two inner chain plates; the inner chain plates, the outer chain plates and the roller are connected by use of a pin shaft; an oil storage chamber is arranged in the roller and communicated with a pin hole formed in the roller; sealing rings are arranged on the two ends of the first position of the pin shaft; the conveying chain is capable of sealing the lubricating oil around the pin shaft without leakage, and the conveying chain does not need to be lubricated for a long time, and therefore, the cost is saved and the efficiency is improved.
