The shock absorbers have a limited lifespan, depending on the
load. For this reason, their function should be checked regularly.
The shock absorber is working correctly if the unit moves gently to
the end positions. When replacing it, observe the control number
"-446" at the end of the damper designation. These specially
tested shock absorbers are only to be ordered from SCHUNK.
When replacing a damper, the complete additional parts list for
hydraulic dampening should be ordered.
Proceed as follows with the replacement:
Ø
Remove the compressed air lines.
Ø
Loosen the counter nut (124).
Ø
Remove the shock absorber (121) from the unit and remove the
sleeve (122). If the latter cannot be loosened from the shock ab-
sorber, it may be helpful to use a small bar magnet or turn the
unit by hand.
NOTE
If the shock absorbers are installed vertically (horizontal axis of ro-
tation of the module), make sure that the sleeve (122) and the
ball (142) are secured against falling out.
Clean all parts thoroughly and check all parts for defects and wear.
