CAUTION
D
 Incorrect transportation of couplings
72
Ensure that the coupling is correctly transported.
CAUTION 78
89
Material damage to coupling components can occur as a result
of:
T1
 Contact with sharp-edged objects

Protect coupling components for transportation.
Only hoist coupling components with nylon belts or ropes.
ef
Always cushion parts when supporting them from below.

Following transportation damage:

 Check the coupling carefully for damage.
Consult the manufacturer (Address see chapter 1).
tte
3.3 Storage
Le
CAUTION
ai
Material damage to elastic elements and rubber parts can occur

as a result of:
gh
 Incorrect storage

at
 Compact, short design – connection dimensions in accordance with SAE J 620
or for connection of two shafts
D
 Free axial movement
 All-round ventilation (cooling) of the rubber washer
72
 Suitable for high speeds
 Large admissible bores
 78
Simple mounting - axial plug-in capability

89
4.2 Specifications
T1
Admissible ambient temperatures:

NR: -45°C to +80°C (temporary maximum temperature 100°C)
SI: -45°C to +130°C

5 Alignment of the units being connected
U
IMPORTANT
-A
 The units should be aligned during assembly.
16
 The overall misalignment is composed of the misalignment and the operating
misalignment. The permissible overall misalignment values can be found in the
catalogue and must not be exceeded.
ed
Align the units that are to be connected as accurately as possible. In this way, a
long service life for the coupling and maximum operating misalignment values can
be achieved.
at
After completion of assembly, check the alignment of the coupling again and if
necessary correct.
D
5.1 Axial alignment
72
Determine the axial misalignment (see Fig. 5-1).
 78
Take installation length L from the installation drawing.
 Align the units (installation dimension = L±∆KA max).

CAUTION
-A
Material damage to elastically installed motors can occur as a
16
result of:
 Disregard during alignment of the extent by which the motor
bearing settles
ed
During vertical alignment, take into account the extent by which the
motor bearing settles. Please enquire about specifications for the
at
degree of settling from the motor manufacturer or motor bearing
manufacturer.
D
Measure the radial misalignment with a dial gauge (see Fig. 5-2).
72
 Attach the dial gauge to the hub.
 Set the sensor of the dial gauge radially against the centering.

78
