ABSTRACT:
A split, circular flanged bushing for securing driving or driven elements such as sheaves, pulleys, and the like to a rotatable shaft, having an integrally formed key in the center opening of the bushing for insertion in a corresponding keyway in the shaft. The bushing is formed in a sintering operation and increased density is imparted to fillets or junctions between the flange and the outer wall of the body, thereby providing increased resistance to stress fatigue in these critical areas. Fillets between the key and the inner wall of the body are provided to distribute the stress concentration inherent in these areas.
