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 DSD10 and DSD12 have one set screw on each end. DSD16, DSD21, DSD26, DSD32 and DSD36 have set screws 90° apart.
Note 3 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4 Couplings supplied with aluminum hubs and electrically isolating (Acetal) center spacers. Stainless steel hubs available upon request.
