The purpose of this paper is to investigate the influence of the number of links on the fatigue strength of single and double strand roller chains. In this paper, at first the theoretical expres-sion for the relation between the fatigue life distribution and the number of links is developed on single and double strand roller chains. Then the behavior of the fatigue life distribution is investigated experimentally. Also the influence of the number of links on the fatigue limit has been examined, and discussed the fatigue limit reduction factor. The results are as follows. (1) The relation between the fatigue life distribution and the number of links of single and double strand roller chains can be explained by assumption of the Weibull distribution. (2) The fatigue limit of double strand roller chain doesn't become twice as much as the fatigue limit of single strand roller chain, and fatigue limit reduction factor become the values from 1.25 to 1.45. (3) The tensile strength, the fatigue strength at a certain cycles and the fatigue limit of single and double strand roller chains decrease, as the number of links increases.
