The KTR-SI FRE is an idle-rotation overload system with a high level of repeat accuracy. In the event of overloading, the idle rotation elements uncouple the driving and driven side, reliably protecting against damage. Once the overload has been eliminated, the idle rotating elements are manually re-engaged so that the drive is released again.

Properties:

• Idle-rotation overload system (load-separating) 
• Good repeating accuracy
• Flange design for the attachment of pulleys or chains wheels
• Can be combined with ROTEX®, GEARex® or RADEX®-N
• The intelligent further development of the shear bolt coupling and hydraulic overload system
• Setting range up to 60,000 Nm (higher torques on request)

Please refer to the respective data sheet for the properties of the individual couplings.
