Note 1 | Torque ratings are at maximum misalignment. |
Note 2 | Performance ratings are for guidance only. The user must determine suitability for a particular application. |
Note 3 | Torque ratings for the couplings are based on the physical limitations/failure point of the machined beams. Under normal/typical conditions the hubs are capable of holding up to the rated torque 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. Please consult technical support for more assistance. |
