Zusammenfassung:A belt pulley (1) for a belt drive and a plastic injection molding method for producing the belt pulley are provided. The belt pulley (1) includes an anti-friction bearing (2) and a running ring (3) which surrounds the bearing outer ring (7). An end side of the running ring has a multiplicity of molding points (13) which run on the sector radii (R) of circular sectors which have a common center point on the rotational axis (15) of the belt pulley and at least two center point angles (α) of different size. Part of the circular sectors are to have sector radii, on which the molding points have cross sections of different size. Here, the center point angle of the adjacent circular sector on the side of the larger molding cross section is larger than the center point angle of the adjacent circular sector on the side of the smaller molding cross section.
