STOP
The maximum permissible bore diameters d (see 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).
•
Make absolutely sure to observe the figures for Ø d
max
.
•
Carefully align the hubs when the finish bores are drilled.
•
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 marked with the symbol
.
Reference to unbored resp. pilot bored coupling components with explosion protection
marking:
Basically the company KTR supplies couplings resp. coupling hubs with explosion protection
marking as an unbored or pilot bored type only on explicit request of the customer. The prerequisite
is a declaration of exemption submitted by the customer assuming any responsibility and liability for
remachining performed properly.
