3. Characteristics of KTR Rotex ZR Flexible Coupling:
– Rotex ZR Flexible Jaw Couplings are manufactured by KTR/Germany.
– Compact design flexible couplings.
– High-temperature resistant material T-PUR, available in various hardness levels.
– ATEX compliant (according to EU Directive 2014/34/EU).
– No maintenance required and easy to maintain.
– Used in elevator traction and conveyor systems.
– The KTR Rotex ZR shaft coupling ensures the transmission of reduced torsional force and absorbs vibrations caused by uneven machine operation. The elastic material deforms under load and high speed. Sufficient expansion space must be provided.
– All sizes of Rotex elastic couplings have a maximum torsional angle of 5°. They can be mounted both horizontally and vertically.
– This shaft coupling is characterized by long lifespan and sound operational characteristics produced by the entire manufacturing process.
– The elastic material between the coupling centers helps reduce corresponding torsional vibrations in the transmission system. The material is heat-resistant, with various hardness levels available. Rotex flexible torsional couplings are used in most general machinery and plant engineering applications.
