Between counterbore diameter: first end, 2.7495 in. And 2.7500 in. ; second end, 1.875 in. ; counterbore depth: first end, 0.313 in. and second end, 0.563 in. ; distance from center of bore to bottom keyway: 0.999 in. ; flange width: 2.625 in. ; hub diameter: 3.000 in. ; 1 keying facility provided; keying facility width: 0.375 in. ; keying facility length: 4.000 in.
A device for connecting the ends of two shafts to produce in effect, one piece of rigid shafting so that the rotary motion of one shaft is transmitted to the other shaft. Couplings of the sleeve type must have an over-all length exceeding the outside diameter, or must have an internal spline.
