A diameter dimension of a chamferwhich is formed on axial end faces of a cylindrical rollerwhich is retained in each pocketof a cagewhose axial positioning is realized by a roller guide at a portion which lies closer to an outside diameter side thereof is made such that a central flat surfacewhich lies on an inside diameter side of the chamferis not exposed from an external surface of an outside diameter side flat plate portion. Then, a difference between a minimum value &#x394;of an amount by which the cylindrical rollerprojects from the external surface of the outside diameter side flat plate portionand a dimension Wof the chamferwith respect to a diameter direction thereof is made smaller than a thickness Tof the cage

Thrust cylindrical roller bearing

Into a raceway groove formed between outer and inner races, there are incorporated a plurality of rolling elements of which outside diameters serving as the rolling contact surfaces thereof each has a curvature in the axial direction as well and also each of which has a radius smaller than the radius of the raceway surfaces of the outer and inner races. The rolling elements are arranged in such a manner that the mutually adjoining rolling elements cross each other alternately and also that the outside diameters of the respective rolling elements are always contacted at two points with the raceway surfaces of one race and the raceway surfaces of the other race.
