Universal Joints


  • Can accommodate extremely large angular misalignments
  • Can accommodate extremely large radial misalignments, when used in pairs


  • Does not transmit rotation homokinetically (so that the two shafts rotate at exactly the same speed throughout rotation), unless used in pairs, in a specific arrangement

Typical Applications:

Can be used as a linkage, or transmission, between two intentionally misaligned shafts, rather than just as a flexible coupling (meant to accommodate very small misalignment that inevitably but unintentionally results from tiny mounting errors and thermal growth.)
