Dimensions are for references only and are subject to change without notice unless certified. Size 1020 thru 1230T10 covers are cast aluminium alloy; Size 1240 thru 1260T10 covers are fabricated steel.
* Maximum bore are LESS than shown above for hubs with an INTERFERENCE FIT and a set screw OVER the keyway; refer to Engineering 427-105 for details. For the above Max Bores, Sizes 1020 thru 1090 will be furnished for CLEARANCE FIT with a set screw OVER the keyway. Sizes 1100 and larger will be furnished for INTERFERENCE FIT without a set screw. Folk standards apply unless otherwise specified. Recommended key sizes for above maximum bores are listed in Table 14 on Page 21. For other maximum bore-key combinations that can be manufactured to order, refer to Table 9 on Page 20.
● Maximum bore is for hub with keyway for rectangular key.
Minimum bore is the smallest bore to which a RSB (rough stock bore) hub con be bored. Depending upon coupling size, rough stock bore hubs hove only a blind centering hole or a small through hole that will permit rernachining of the hubs to the minimum, bores specified. RSB hubs ore not drilled and topped for set screws.
□ Torque rating values for hubs with Taper Lock bushings differ from those shown above; refer to Table 13 on Page 21.
Consult Factory for speeds higher than those shown.
