On Steel Belt No.14 Welded Endless Belt #4

Above is a figure of stress (S) against the number of cycles to failure (N).
This curve begins to get flat at over one million bendings and becomes flat at over ten million bendings.
Pulley diameter = Belt thickness x 700

Coefficient 700 is set to make the same stress as the one in the chart above so that the belt endures 10 million bendings.

When bendings are not so many,
700 can be 600 or 500
This is to be discussed and adjusted when we decide belt specifications.
