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. Stainless steel hardware is available upon request. MWC series parts have two socketed head cap screws on each end.
Note 3 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4 Coupling torque and torsional stiffness are determined by the largest bore selected.
Note 5 Shafts may penetrate up to 0.5 x L. Be certain shafts do not touch.
