ACCESSORIES DAMPING RINGS
Positioned between the bell-housing motor flange and lid of the tank,
they help to reduce the transmission of the vibrations and emission of
noise generated by the system.
Damping rings provide a perfect hydraulic sealing actions by virtue of
their special profile; damping rings are available for IEC electric motors
from size 80 to size 315.
In order to warranty the application, to proceed with the calculation of the
max weight and moment with the following formulas.
Values higher than those in the table could damage the product and
couldn’t warranty the conformity of the application!
