TT-3X-01 - Miki Pulley Vietnam - STC Vietnam

Overloads are detected accurately and the drive key removed from the groove to cut off input and output. Once the overload is resolved, operation can continue automatically at the same torque from the same indexing position.Torque is set using a built-in torque spring, so there is no troublesome fine-tuning. The TT-01 type is used for two-shaft butt connection and also serves as a flexible coupling.
