Table Notes:
  1. Peak torque. Select a size where Peak Torque exceeds the application torque x service factor.
  2. Max. compensation values are mutually exclusive.
  3. Torsional stiffness values apply at 50% peak torque with no misalignment, measured shaft-to-shaft with largest standard bores. Note that in some vendors' catalogues the given torsional stiffness applies to the un-mounted bellows element only, an unrepresentative calculated value.
