STEP 1: Fill out the Application Worksheet.
STEP 2: Looking at the Mounting Diagrams along each
side of the Selection Guide, select the diagram that best
fits the application. If the System Natural Frequency from
the Application Worksheet is higher than the values
shown in the Selection Guide and the Temperature Range
is acceptable, select the smallest model series that will
carry the Load required for the application. Refer to the
Data Sheet in the pocket on Page 4 for more information
on the selected series.
If the mount that you have selected does not meet the
above criteria, select another mount and repeat the
selection process. If you have special requirements,
send Corry Rubber Corporation your completed
Application Worksheet and an Applications Engineer
will contact you with a solution.
STEP 3: On the Data Sheet, consult the Load vs.
System Natural Frequency Graph for the required
Mounting Oreientation. Locate the intersection point of
the System Natural Frequency (fn) and the Supported
Load per Mount (W) calculated for the application. The
Model Number represented by the line at, or dierectly
below, this intersection point is the best choice for the
STEP 4: Where required, select the desired Hardware
Options from the data sheets. If no hardware options are
available, place “00” in the Hardware Options portion of
the part number. Specify metric or imperial model. *(See
Ordering information on Page 4).
*NOTE: Stud, Machinery, and Leveling Mounts must
include metric or imperial designation. Plateform,
Multiplane, Low Profile, Ring and Bushing and
Centerbond Mounts do not require metric or imperial
A 200 lb (890 N) pump turning at 1725 RPM is causing
vibrations which are affecting the readings of nearby
sensitive equipment. In order to control these vibrations,
isolation mounts will be placed under the base. A 1/2”
diameter bolt hole exists in the center of each of the 4
legs of the base. The isolators will be bolted to the floor.
The ambient temperature around the motor is 65°F to
185°F (18°C to 85°C).
STEP 1: From the Application Woksheet, we know:
• Working Temperature Range = 65°F to 185°F (18°C to
• System Natural Frequency for 80% isolation (fn) = 9.6
• Supported Load per Mount (W) = 50 lbs (220 N)
STEP 2: From the Selection Guide, we conclude:
A Machinery Mount can be used in this application.
• The geometry will work.
• The Lowest System Natural Frequency for Machinery
Mounts is lower than the Calculated Natural Frequency for this application.
• The EMM20N Series has a mount which will carry the
Required Supported Load.
STEP 3: From the EMM20N Machinery Mount Series
Data Sheet, we determine:
• The model number EMM20N - 0060 mount is the best
STEP 4: From the Hardware Options & Ordering
Information sections, we conclude:
• There is no optional hardware required for the
• An Imperial mount specification is needed.
• Four EMM20N - 0060 - 00 - I elastomeric isolation
mounts should be ordered.
