Having started up the coupling, the tightening torque of the screw connections has to be 
inspected at regular maintenance intervals. 

 
 
 

 
The displacement figures specified in table 12 provide for sufficient safety to compensate for external influences 
like, for example, thermal expansion or foundation settling. 
 

 

 

 

In order to ensure a long service life of the coupling and avoid dangers with the use in 
potentially explosive atmospheres, the shaft ends must be accurately aligned. 
Please absolutely observe the displacement figures specified (see table 12). If the figures 
are exceeded, the coupling will be damaged. 
The more accurate the alignment of the coupling, the longer is its service life. 
If used in potentially explosive atmospheres for explosion group IIC, only half of the 
displacement figures (see table 12) are permissible. 

 

Please note: 

  The displacement figures specified in table 12 are maximum figures which must not arise in parallel. If radial, 

axial and angular displacement arises at the same time, these values must be reduced (see illustration 34). 

  Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified 

in table 12 can be observed.
