Between xcounterbore diameter: 2.550 in. And 2.570 in. ; counterbore depth: 0.340 in. And 0.360 in. ; flange width: 0.340 in. And 0.360 in. ; hub diameter: 2.550 in. And 2.570 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.
