PURPOSE:To aim at improvement in the setting efficiency of rolling elements, by holding the requisite number of rolling elements is a support in advance and after these rolling elements are assembled together with the support, melting this support. CONSTITUTION:A support 1 consisting of thin water soluble polyvinyl material is formed so as to hole the requisite number of rolling elements 2 to be set as coded into an insetting form. These rolling elements 2 are holded in this support 1 in advance, and these rolling elements 2 are inset in an insetting part 4 of a bearing body 3 together with the support 1 like ordinary assembling. Afterward, when this assembled bearing body 3 is dipped in a water tank, this water soluble support 1 is melted away into the water, thus the desired bearing is securable.
