Note 1 Static torque 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 a black oxide finish and Nypatch® socket head cap screws. Stainless steel hardware is available upon request.
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 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.
