A method for assembling a shell-type needle bearing (10) which eliminates the need for a plating step as in the prior art, by using reducible-diameter retainers, and by assembling the retainers (13, 18) and the needle (12) after both flange parts (11b, 11c) of an outer ring (11) of the shell have been formed and heat-treated. In addition, because the retainers (13, 18) are not affected by heat from the heat treatment a resin material can be used as the material for the retainers (13, 18). |
