Features of ZTK series

Backlash-free flexible couplings: ZTK series. Features are the construction of a metal coupling half and elastic characteristics of the flexible insertion.
●Providing the connection without a backlash;
●High wear resistance and reliability in comparison with the high torsional strength;
●Service and repair are not required;
●Flexible insertion smooths out the impact loads;
●Identical characteristics at the mode of constant rotation and reverse;
●Oil resistance and electrical insulating properties;
●Working environment temperature: -30℃~80℃.

Flexible insertion


Scheme of ZTK flexible insertion

The flexible insertion is made without a hole in the form of five-pointed star, that simplifies its installation. The width of the flexible insertion is larger than the known analogs have, that prevents the skewing at the docking of the coupling halves.


Vibration isolation of the coupling halves due to backlash "S" at the docking of the coupling halves.
