Installation instructions
Before installation and use check whether the identification
number on the damper or on the packaging matches the respective
designation on the delivery note. Industrial shock absorbers are
maintenance-free and ready to install.
Operating temperature range:
-12 °C to 66 °C
Mounting:
As required but always in such a way that the entire
damper stroke is used. The dampers must always be mounted in
such a way that the forces are introduced centrally over the piston
rod. The maximum permissible side load angle (see table) must
not be exceeded. If there is a side load angle, it generally leads
to a reduction in service life. In the case of maximum permissible
values being exceeded a side load adapter must be used.
Self-compensating:
The MC range of shock absorbers is
self-compensating. In a selectable range according to a table, the
different effects of power, weight, temperature and speed balance
out independently. The shock absorbers are divided into five
hardness ranges (me min. to me max.) as standard. The grading
ranges from -0 (very soft) to -4 (very hard).
WARNING
Temperature effect: The W
4
and me values given in the
performance table (see manual or catalogue) are valid
for room temperature. Deviating values apply to higher
temperatures.
During installation of the dampers moving masses can
lead to injuries due to inadvertent starting. Secure moving
masses against inadvertent moving.
The dampers may be unsuitable for use and have an
insufficient damping effect. Check the specific suitability
of the dampers before installation.
If operated outside of the operating temperature range,
the damper can lose its function. Operating temperature
range must be maintained. Do not paint dampers due to
heat emission.
Fluids, gases and dirt particles in the surrounding area can
attack or destroy the seal system of the damper and cause
it to fail. Protect or encapsulate piston rod and seal system
from external materials in the surrounding area.
Damage to the piston rod surface can destroy the seal
system. Do not grease, oil piston rod etc. and protect
against dirt particles.
The piston rod can be torn from the damper. Do not load
the piston rod with tensile stress.
Damper can tear off upon impact. Always lay out the
connection structure in such a way that the maximum
occurring forces can be absorbed with sufficient safety.
The maximum reacting forces listed in the calculation range
may deviate from the actually occurring reacting forces, as
these are based on theoretical values.
Commissioning
- After installation, start a test run of the moving mass at reduced
operating speed to begin with.
During the test run
- Gradually accelerate the load capacity up to the subsequent
operating speed. You can find this in the calculation for your
application. In the correct final setting, the piston rod of the
shock absorber reaches the end position (positive stop) without
a hard stop.
