The maximum permissible bore diameters d (see table 1 or
3 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 (steel hubs) machined by the customer have to
observe concentricity or axial runout, respectively (see
illustration 8).
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 transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his
responsibility.
