Note 1 Static torque ratings are at maximum misalignment. To obtain dynamic rating, static ratings should be divided by 2 for non-reversing applications and by 4 for reversing applications.
Note 2 Hardware is alloy steel with black oxide finish. Parts ISR6, ISR8, ISR10, and ISR12 have one set screw on each end. ISR14, ISR16, ISR18, and ISR20 have two set screws on each end 120° apart.
Note 3 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4 ISR6, ISR8, ISR10, ISR12 have one set of two spiral cuts.
