Two shaft hubs (type R) will always be supplied unless ordered “LESS SHAFT HUBS”.<br />
(1) All finish bores will be for clearance fit with set screw over the keyway unless ordered otherwise.<br />
(2) Minimum shaft separation is obtained by allowing the shafts to protrude slightly beyond the faces of the type R shaft hubs.<br />
Hub separation C and dimension L must be maintained as listed.<br />
(3) Standard shaft separations are obtained when type R shaft hubs are mounted flush with shaft ends. In this case the shaft separation is the<br />
same as the hub separation, dimension C.<br />
(4) Maximum shaft separation is obtained by allowing type R shaft hubs to slightly overhang their shafts. Maximum hub separations tabulated, are<br />
based on an overhang of 1/4” or less per hub. Excessive shaft hub overhang increases hub and key stresses.<br />
(5) Interference fits up to .0005”/in. of shaft diameter are permissible providing maximum bore with interference fit is 1/4” less than maximum<br />
clearance fit bore indicated by note (a).<br />
(6) Weight shown is total coupling weight based on maximum bore.<br />
