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 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 3 Our standard couplings are supplied with black anodized aluminum hubs. Stainless steel hubs are available upon request.
