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 PSMR10, PSMR13, PSMR16 and PSMR19 have one set screw on each end. PSMR22, PSMR25, PSMR29 and PSMR32 have two set screws 120° apart.
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.
