A scroll compressor has an eccentric pin that extends forwardly of a rotating shaft. The eccentric pin generally has a curved outer portion and a flat outer portion. Each of the flat and curved outer portions have fillets that are formed to merge the eccentric pin portions into an end surface or shoulder on the shaft. The fillets are formed to have a relatively complex shape with more than a single radius of curvature. In one embodiment, there are two radii of curvature, with a greater radius of curvature formed to extend from an outer periphery of the eccentric pin, and merge into a second portion having the lesser radius of curvature that merges from the first portion downwardly into the shoulder. In a second embodiment, the fillet generally has the shape of one quarter of an ellipse.
