The maximum permissible bore diameters d (see table 1 
and 2 in chapter 1 - technical data) must not be exceeded. 
If these figures are disregarded, the coupling may tear. 
Rotating particles may cause danger to life. 

 

  Hub bores machined by the customer have to observe 

concentricity or axial runout, respectively (see illustration 
4). 

  Please make absolutely sure to observe the figures for 

Ø d

max

  Carefully align the hubs when the finish bores are drilled. 

  Please provide for a setscrew according to 

DIN EN ISO 4029 with a cup point or an end plate to fasten 
the hubs axially.

The customer bears the sole responsibility for all machining processes performed 
subsequently on unbored or pilot bored as well as finish machined coupling components 
and spare parts. KTR does not assume any warranty claims resulting from insufficient 
remachining.

If a feather keyway is intended to be used in the hub, it should correspond to the tolerance ISO JS9 (KTR 
standard) with normal operating conditions or ISO P9 with difficult operating conditions (frequently alternating 
torsional direction, shock loads, etc.). The keyway should preferably be located between the cams. With axial 
fastening by setscrews the tapping should be located on the keyway except for Al-D which should be located 
opposite the keyway. 
 
The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his 
responsibility.
