How to Choose the Right Bellows Coupling

When selecting a bellows coupling, several parameters and conditions must be considered:

  • Torque Requirements: Ensure the coupling can handle the maximum torque of your application to prevent failure or damage.
  • Misalignment Compensation: Assess the types and extents of misalignments (radial, axial, angular) that the coupling needs to accommodate.
  • Material Compatibility: Choose a material that withstands operational stresses and environmental conditions, such as stainless steel for corrosive environments.
  • Operational Speed: Verify that the coupling can operate efficiently at the desired speed without introducing vibrations or instability.
  • Size and Dimensions: Ensure the coupling fits within the spatial constraints of your equipment setup.
