CODEX STC Accuracy Positioning Torque Limiter (ST4C-ST18C)

CODEX STC Accuracy Positioning Torque Limiter (ST4C-ST18C)

The STC series is an accuracy-positioning torque limiter, coupling type for connecting two shafts while tolerating shaft misalignment. It protects index drives from overload in rotation and thrust directions while transmitting torque accurately without backlash.

Key features

  • Protects index drives and machines from overload
  • Accurate torque transmission with no backlash
  • Positioning accuracy 30 sec (sizes 6-18), repeatability 15 sec
  • Adjustable trip torque by spring and adjusting nut
  • Bore with keyway (K) or power locker (C)
