Engineering Data — Large Flanged Sleeve<br />
Data for couplings with reduced shank diameter hubs.<br />
Depending upon bore, a reduced shank diameter hub (Dimension “N”<br />
or “K”) is available for each coupling, sizes 1160/2160 thru<br />
1300/2300. This provides reduced weight and WR 2 .<br />

See Page 13 for General <strong>Information</strong> and other reference notes.<br />
Hubs with the least possible ‘K” or “N” dimensions for the required bore are normally furnished.<br />
Total weight of coupling varies with “K” or “N” dimensions of rigid and flex hub selection. Add weight of selected hubs to “Sleeve, End Ring and Fasteners” weight.<br />
Note: Maximum bore dimensions are based upon a N/1.4 or K/1.4 ratio. For key and keyway dimensions, consult Falk.<br />
