This paper gives another proof of the existence of axisymmetric traveling fronts. Our method is as follows. We use pyramidal traveling fronts for unbalanced reaction-diffusion equations, and take the balanced limit. Then we obtain axisymmetric traveling fronts in a balanced bistable reaction-diffusion equation. Since pyramidal traveling fronts have been studied in many equations or systems, our method might be applicable to study axisymmetric traveling fronts in these equations or systems. en-copyright= kn-copyright= en-aut-name=TaniguchiMasaharu en-aut-sei=Taniguchi en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword= Traveling front kn-keyword= Traveling front en-keyword= reaction-diffusion equation kn-keyword= reaction-diffusion equation en-keyword=axisymmetric kn-keyword=axisymmetric en-keyword=balanced kn-keyword=balanced END
