Note(1): Priority should be given to values not in ( ). A value in ( ) may be used if necessary.
Note(2): Thickness(t)=1.6mm, may be kept at 1.5mm for the time being. m should be 1.65mm.
Reference 1.The minimum width of the ring of the retaining ring should be less than the plate thickness t.
2.The recommended dimensions of the applicable shaft are given here for reference.
3.d4 (mm) should preferably be equal to d4=d3+(1.4~1.5)b.
