1) When selecting couplings the permanent output of the engine are to be take as a basis. Overloads, peak and short peak outputs acc. to DIN 6271 need no to be taken into consideration.

2) The stated values refer to the dynamic torsional stiffness at f=10HZ and & = 303K ( 30oC) and a test amplitude of 20% TKN.

3) With couplings subjected to high thermal loading we recommended to use 70% CTdyn - for a control calculation very important for applications with constant speed drives.

4) It is not sufficient to consider only permissible vibratory torque. In every case of the power loss loading must be checked and must be within permissible limits ( synthesis value)

5) The values of Pkv in the list of technical data are based on an ambient temperature of 30o C (303 K)
At an ambient temperature of 60o C (303 K)
Pkv60 = Pkv30 . 0,65
At an ambient temperature of 80o C (353 K)
Pkv80 = Pkv30 . 0,40

6) Due to the physical characteristics of the elastic elements tolerance are possible in the mentioned values.

7) The permissible angular and radial displacement depends on the speed. In the speed range upto n= 1500 rpm the a.m. displacement values are valid during the utilization of the nominal capacity. In case of speed exceeding 1500 rpm the displacement ability reduces by 30% each 1000 rpm speed increase.
