Early wear of spider
e. g. contact with
aggressive liquids/oils,
ozone influence, too
high/low ambient
temperatures etc.
causing physical
modification of the
spider
Danger by rotating cam
fragments
1) Set the unit out of operation
2) Disassemble the coupling and remove
residues of the spider
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert spider, assemble coupling
components
5) Inspect alignment, adjust if necessary
6) Make sure that further physical
modifications of the spider are excluded
Ambient/contact
temperatures which
are too high for the
spider, max.
permissible
-30 °C/+90 °C
1) Set the unit out of operation
2) Disassemble the coupling and remove
residues of the spider
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert spider, assemble coupling
components
5) Inspect alignment, adjust if necessary
6) Inspect and adjust ambient/contact
temperature (correct by using other spider
materials, if necessary)
Early wear of spider
(liquefaction of
material inside the
spider cam)
Vibrations of drive
1) Set the unit out of operation
2) Disassemble the coupling and remove
residues of the spider
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert spider, assemble coupling
components
5) Inspect alignment, adjust if necessary
6) Find out the reason for the vibrations
(correct by spider with lower or higher Shore
hardness, if necessary)
!
When operating with a worn spider (see chapter 10.3) proper operation is not ensured.
In respect of environmental protection we would ask you to dispose of the packaging or products on termination of
their service life in accordance with the legal regulations and standards that apply, respectively.
