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.
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 aluminum center spacers. Stainless steel hubs and center spacers available upon request. Insulating (Acetal) spacers available as standard items.
