Torque limiter TT-01 type (two-shaft face-to-face type)

Caution
- The product images are representative only. Specifications may vary by part number, including shape and color.
Product Description
Reliable overload detection and precise operation protect the machine from overload
In the event of overload, the input and output are instantly disconnected to protect the machine.
Because it is a meshing type single position, once the overload is removed, it will automatically re-engage at the same torque and the same indexing position.
Unlike the friction method, it can also be used in harsh environments.
[Features]
· This is a two-shaft face-to-face type, where two shafts are inserted from both ends of the torque tender (housing and hub) and both shafts are secured with set screws, enabling power transmission and protecting the machine from overload.
· Since it is a two-shaft face-to-face type, it can also be used as a flexible coupling as is.
[Applications]
· Semiconductor manufacturing equipment, textile machines, printing machines
