Claim:
A method for assembling a roller bearing including rollers and spacers interposed between adjacent rollers, the method comprising: providing rollers and spacers, each spacer having extended portions at both axial ends thereof; alternately disposing the rollers and the spacers along an inner circumference of an outer ring; mounting a last roller on the inner circumference of the outer ring by arranging two spacers along inner portions of rolling contact surfaces of respective adjacent rollers having been disposed such that the extended portions of the two spacers contact end faces of the respective adjacent rollers and the two spacers can freely revolve around the respective adjacent rollers; and inserting the last roller between the two arranged spacers toward the outer ring so that the two spacers are placed on both sides and are allowed to slide, wherein the extended portions of each spacer having been disposed contact end faces of the adjacent rollers, wherein the extended portions have a size which allows the two spacers to revolve around the last roller without interfering with each other as the last roller is inserted, and wherein the outer ring has a raceway surface and rim portions extending radially inwardly from the raceway surface, and each extended portion has a face which contacts one of the rim portions.
