MaterialKeys are to be carbon steel or alloy heat treated steel as specified. Carbon steel keys are to be0.30 carbon minimum, with hardness of Rock
5、well B 90 minimum. Alloy steel keys are to be SAE 2330 or 8630steel, heat treated to a hardness of 40-50 RC; or other alloy steels having equal physical properties at thesame hardness. Alloy heat treated keys are to be marked with depressions on the top to distinguish them fromcarbon steel keys.4. D
6、imensionsDimensions are to be as given in Tables 1A, 1B, and 2 and Figures 1, 2, and 3.4.1 Width A (Shown in Illustrations Accompanying Tables)Values shown were set with the maximum keyslot width as that figure which will receive a key with the greatest amount of looseness consistent with assuringth
7、e keys sticking in the slot. Minimum key slot width is that figure permitting the largest shaft distortionacceptable when assembling maximum key in minimum key slot.4.2 Dimensions A, B, C, and EThese dimensions are to be taken at the side intersection.FIGURE 1SAE J502 Revised SEP72-2-TABLE 1AKEY DIM
