1.Features

  • Mounted on the shaft, capable of transmission through roller chains, belts, and gears
  • All Torque Limiters are automatic safety devices to prevent overload, providing reliable operations and adjustable functions
  • The Torque Limiter with a sprocket is standardized, saving you the hassle of machining and assembly
  • Reliably protects your machine through easy handling
  • Automatically resets without trouble
  • Can be used in combination with each type of drive
  • A variety of standard items are available

2.Structure

Structure
  • During normal operations, the center member is put between the friction facings while being pressured by the disk spring. Below the set torque, the friction force transmits rotation.
  • During overload, if the operational torque exceeds the set torque, the center member slips between the friction facings.
