Connecting Shaft

line shaft, distance coupling, connection coupling, longtype coupling, hollow shaft, hollow shaft connection coupling, lined shaft, lengthy coupling, lengthy shaft coupling, ISO 9001, ISO 14001, Korean made components, IT components, mechanical components, motion components,motion accessories, motion control, motion control components, semi conductor components, display machine components, small sized machine components, small mechanical components, machine components, factory automation part

Connecting shaft is a compact solution which enables to transmit
motion accurately, especially when there is a longer distance
between shafts of an application.

  • Why Connecting Shaft?
  • How to determine the proper length(L)
  • How to calculate permissible parallel misalignment
  • How to calculate Torsional Stiffness

  • Please modify rated/max. torque value with temperature correction factor when it’s higher than 30ºC.
  • Max. torque/rated torque is the value regarding to a coupling’s self-durability and is not related to slip-torque between the coupling bore and the shaft.
  • Please contact Sung-il Customer Service team for the special lengths (out of range).
