STOP
The maximum permissible bore diameters d (see table 1
to 5 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
9).
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.
KTR supplies unbored or pilot bored coupling components and spare parts only upon
explicit request of the customer. These parts are additionally labelled with the symbol
.
