  • Torques from 2.5 to 2,000 Nm

  • Couplings for automation engineering, power transmission, medical technology

RADEX-NC (Application)

A typical application of the RADEX®-NC are backlash-free worm gear pairs with low transmissions. The rigidity of the coupling must be converted by reason of the transmission of the gearbox from the drive side to the driven side.

Here the transmission itself has a decisive influence because it is squarely included in the calculation. This converted rigidity is added in line to the gearbox stiffness in order to get the total rigidity. In case of transmissions that are lower than i = 8 we recommend to use the RADEX®-NC due to the loss of rigidity of the total system if flexible couplings are used.

Explosion protection use

This type is certified and confirmed according to directive 2014/34/EU as unit of category 2G/2D and thus suitable for the use in hazardous areas of zone G1, G2, D21 and D22.

If clamping ring hubs without keyway (only permitted for category 3) are used in hazardous areas the coupling must be designed in a way that between the peak torque including all operating parameters and the torque of frictional engagement and the nominal torque of the coupling, resp., there is a safety of at least s=2.

Please read through our information included in the respective Type Examination Certificate and the operating and mounting instructions!
