||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.
||Hardware is alloy steel with black oxide finish. PSR6, PSR8, PSR10, and PSR12 have one set screw on each end. PSR14, PSR16, PSR18, and PSR20 have two set screws on each end 120° apart.
||Performance ratings are for guidance only. The user must determine suitability for a particular application.
||Coupling torque and torsional stiffness are determined by the largest bore selected.
||Torque ratings for the couplings are based on the physical limitations/failure point of the machined beams. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the machined beams. Keyways are available on straight bore couplings upon request. Please consult technical support for more assistance.
