FLEXIBLE COUPLINGS HADEFLEX® X / TX

HADEFLEX® – FLEXIBLE COUPLINGS The flexible Hadeflex® couplings are claw couplings with a flexible element to provide a torsionally flexible connection for shafts. The flexible elements excel in their wear resistance, their oil, ozone and ageing resistance and their temperature resistance from –20 °C to +80 °C. Thanks to their flexibility, impacts, rotary vibrations and noises are effectively absorbed. The flexible elements are dimensioned such that radial, axial and angular movements between the two halves of the coupling are cancelled out. The flexible Hadeflex® couplings are of the...
