4.2 Hint Regarding the Finish Bore 

 

STOP 

 

D A N G E R !  
The maximum permissible bore diameters d (see 
table 1 to 3 in chapter 1 - Technical Data) must not be 
exceeded. If these figures are disregarded, the coupling 
may tear. Rotating particles may cause serious danger. 
 

  Clamping hub bores machined by the customer have to 

observe concentric running or axial running, respectively 
(see illustration 10). 

  Please make absolutely sure to observe the figures for 

d

max

  Carefully align the clamping hubs when the finish bores 

are brought in.

and axial running

 

 

 

C A U T I O N !  
The orderer is responsible for all subsequently made machinings to unbored or pilot bored 
and to finish machined coupling parts and spare parts. KTR does not assume any warranty 
claims resulting from insufficient refinish. 

 

 

P R E C A U T I O N !  
Any mechanical rework to couplings that are used in hazardous areas require an explicit 
release by KTR. 
The orderer must send a drawing to KTR acc. to which the manufacture must be made. KTR 
checks this drawing and returns it to the orderer with approval. 
KTR supplies unbored or pilot bored coupling parts and spare parts on explicit customer´s 
request. These parts are additionally labelled with the symbol 

 
 
 

4.3 Assembly of the Hub 

 

 

A T T E N T I O N !  
We recommend to check bores, shaft, keyway and feather key for dimensional accuracy 
before assembly. 

 
Heating the hubs slightly (approx. 80 °C) allows for an easier installation onto the shaft. 
 

 

P R E C A U T I O N !  
Please pay attention to the danger of ignition in hazardous areas. 

 

STOP 

 

D A N G E R !  
Touching the heated hubs causes burns. 
We would recommend to wear safety gloves. 

 

 

C A U T I O N !  
During the assembly please make sure that the E

DK

 or s dimension (see table 1) is observed, 

so that the coupling parts do not contact each other during the operation. 
Disregarding this hint may cause damage on the coupling.
