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.
Illustration 9: Concentricity and axial run-out
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 bore is drilled.
The bore tolerance should preferably be selected as per table 8.
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 standard operating conditions or ISO P9 with complicated operating conditions (frequently
alternating torsional direction, shock loads, etc.). In this case the keyway should be flush with one of the locating
bores for the pins. With axial fastening by the setscrew the tapped hole should be located on the keyway.
The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his
responsibility.
