<P>PROBLEM TO BE SOLVED: To prevent the generation of an edge load at a positioning protruded portion or at the peripheral edge of a depressed hole or a through-hole in a raceway surface formed when providing a pin, and between these areas and rolling rollers. <P>SOLUTION: A shoulder R portion 8a is provided at the peripheral edge of the depressed hole 8 which is formed in the raceway surface 1a when applying embossing work to the raceway surface 1a of a bearing ring 1 as a pressed molding to form a protruded portion 6 protruded on the back-side outer diameter face. At the peripheral edge of the depressed hole 8 in the raceway surface 1a, no edge load is generated between the edge and the rolling rollers 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
