Some of the items are scheduled to be discontinued as of end of March in 2023. The manufacturer keep the items produced but they are not available with Misumi.
There are not the replacement items and the plan to resumption of sale. Please check the quotation and order screen for details.

Securely detect overloads
Precise operation to protect machinery from overloads

Instantaneous input and output disconnection upon overload to protect machinery. Because the interlocking type system is single-position,
removing the load automatically creates a connection with the same torque and at the same index position. Unlike a friction system,
accommodates even poor conditions.

Applications: Semiconductor manufacturing equipment, fiber equipment, printing equipment

TT-□-01 Type
2-axis butt type with 2 shafts inserted from both ends of the torque tender (housing and hub) and both shafts fixed with set screws to protect machinery from power transmission and overloads.

As a 2-axis butt type, this can also be used as a flexible coupling.
