- Performance ratings are for guidance only. The user must determine suitability for a particular application.
- 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.
