Notes

Notes 

  • Static Breaking Torque is not recommended operating torque.
  • Square and hex bore measured across the flats.
  • Maximum operating angle for transmission of power is 25°.
  • For greater angular operation, use double universal joint. Join two universal joints back to back and connect with a short shaft. Attach universal joints to shaft by drilling and pinning.
  • Swing Diameter is the maximum diameter over bearings, clearance must be allowed.
