DATAFLEX

 is a low-maintenance torque measuring shaft. We recommend to perform a visual inspection on the 

torque measuring shaft 

at least once a year

. Please pay special attention to the condition, alignment and screw 

connection of the torque measuring shaft and the condition of the lamina sets of the RADEX

®

-N coupling. 

 

 

 

Having started up the torque measuring shaft the tightening torques of the screws have to 
be inspected during the usual inspection intervals. 

 

 

Please consider our operating/assembly instructions KTR-N 47110 additionally when using 
the RADEX

®

-N coupling. 

 
 
 
 

 
If requested, we are pleased to perform the calibration of your torque measuring shaft and other services.
