** All Force values in the Selection Chart are based on a maximum operating pressure of 100 psi (7 bar). Actual force capabilities of the Air Spring depend on the airpressure available. The Corrected Force calculation compensates for available air pressure.

** Working Temperature Range for Sleeve Type and Bellows Type YI-1B5, YI-1B6, YI-1B7, YI-1B8; YI-2B6, YI-2B7, YI-2B8 is -40°F to 210°F (-40°C to 100°C). WorkingTemperature Range for all other Air Springs is -65°F to 160°F (-55°C to 70°C).

Sizing Instructions

Step 1: Fill out the Application Worksheet.

Step 2: In most applications a constant actuation force over thestroke is not required and sizing should begin with Single ConvoluteBellows Type Air Springs. However, if a constant actuation force overthe stroke is required, consider only the Sleeve and Rolling LobeType Air Springs.

Step 3: Refer to the Selection Chart under Actuation Specifications.In the Force (lbs) At A Stroke Of: Data Table choose the column thatis equal to or exceeds the Stroke Required (S) (i.e., if a stroke of 2.5 inches (64 mm) is required, refer to the 3.0 in. (75 mm) column). Identify the first Air Spring model that will generate a forceequal to or greater than the Corrected Force (F

C) required. This is the

Air Spring that will best serve your application. Select a model thatincludes an internal bumper if one is needed in the application.Availability of internal bumpers can be found under the FeaturesTable for each Air Spring.

Step 4: Verify the Envelope Dimensions of the selected Air Springto ensure that the Air Spring will fit the application. Allow a two inch(50 mm) clearance on the diameter to prevent abrasion of the flexmember. Select the Model Number that provides the Features andMounting Dimensions required for the application.

Installation Consideration

• External extension stops are required to limit the extension of theAir Spring(s).

• The path of motion must be guided as Air Springs provide little lateral stability.

Sample Problem

A 3100 lb (13,789 N) conveyor carrying an 1100 lb (4893 N) package needs to be lifted 1.8 inches (46 mm) to transfer the package to another conveyor. There will be four Actuators utilized and the warehouse has air lines with 50 psi (3.5 bar). A constantactuation force is not required. Ambient temperature is 68°F (20°C).There is a 12 inch (305 mm) square space to house each Air Spring.Compression and extension stops are provided. Any Air Fitting Portand End Retainer Style would be acceptable.

Step 1: From the completed Application Worksheet, we know:

• Corrected force per actuator is 2100 lbs (9341 N)

• Stroke required is 1.8 inches (46 mm)

• An internal bumper is not required

• A constant actuation force is not required

• Working temperature is 68°F (20°C)

Step 2: A constant force is not needed. Therefore, all Air Springtypes are considered, beginning with Single Convolute Bellows.

Step 3: In the 2.0 in. (50 mm) column under the Force lbs [N] At AStroke Of: Data Table, identify an Air Spring that can generate 2100lbs (9341 N) of force. No internal bumper is required. Model YI-1B6-535 is selected (metric model YI-1B6-835 is selected).

Step 4: The maximum diameter of a YI-1B6-535 is 7 inches (metric model YI-1B6-835 has 178 mm diameter). Therefore, weneed a 9 inch (228 mm) diameter space to house the Air Spring. A 12 inch (305 mm) square space will easily house the Air Spring.Any Air Fitting Port and End Retainer Style would be acceptable. ModelYI-1B6-535 is selected (or metric model YI-1B6-835 is selected).

Sizing Instructions

Step 1: Fill out the Application Worksheet.

Step 2: Refer to the Selection Chart under Isolation Specifications.In the Isolator Load Range @ 100 psi (7 bar) column, identify thefirst Air Spring model that will support the Corrected Load (W

C)

required for the application. Check the Data Table for PercentIsolation at an Input Frequency Of: and compare the Input ExcitationFrequency (f

i) to the input frequencies listed. Referring to the

percent isolation for the model identified, estimate the approximatepercent of isolation. If the first model identified does not meet the isolation requirements, then select the model that will bothsupport the Corrected Load (W

C) and provide the required percent

of isolation. Select a model that includes an internal bumper, if one is needed in the application. Availability of internal bumpers can be found under the Features Table for each Air Spring.

Step 3: Verify the Envelope Dimensions of the selected Air Springto ensure that the Air Spring will fit the application. Allow a two inchclearance on the diameter to prevent abrasion of the flex member.Select the Model Number that provides the Features and MountingDimensions required for the application.

Installation Consideration

• To ensure stability, the distance from the floor to the center ofgravity of the load should not exceed the shortest distancebetween Air Springs.

• Air Springs provide little lateral stability. Therefore, be sure toinclude a method of stabilization.

• Pressurize the Air Spring only when it is loaded.

* All Load values in the Selection Charts are based on a maximum operating pressure of 100 psi (7 bar). Actual load bearing capabilities of the Air Spring depend on the air pressure available. The Corrected Loadcalculation compensates for available air pressure.

** Working Temperature Range for Sleeve Type and Bellows Type YI-1B5, YI-1B6, YI-1B7, YI-1B8; YI-2B6, YI-2B7, YI-2B8 is -40°F to 210°F (-40°C to100°C). Working Temperature Range for all other Air Springs is -65°F to 160°F (-55°C to 70°C).

*** If no air lines are available a tank valve should be utilized; use 100 psi (7 bar) to select an Air Spring.

Sample Problem

Vibrations generated by a pump weighing 8500 lbs (37,810 N)and rotating at 600 RPM are being transmitted into sensitive monitors causing them to malfunction. To control these damagingvibrations, four Isolators located symmetrically about the centerof gravity will be used. The ambient temperature range is 60°F to140°F (16°C to 60°C). Air lines are not available at the site.Therefore, a tank valve will be used. There is the possibility ofdepressurization of the Air Spring. An isolation of greater than90% is required. There is a 9 inch (228 mm) diameter space tohouse the Air Spring. Any Air Fitting Port and End Retainer Stylewould be acceptable.

Step 1: From the completed Application Worksheet, we know:

• Load per isolator is 2125 lbs (9452 N)

• Because a tank valve is being utilized, size using 100 psi (7 bar)

• Corrected load per isolator is 2125 lbs (9452 N)

• Working temperature range is 60°F to 140°F (16°C to 60°C)

• Because of the possibility of depressurization, an internal bumper is required

• Input excitation frequency is 600 CPM

Step 2: The first Imperial Air Spring model that has an internalbumper and is capable of supporting the Corrected Load Per Isolatoris the YI-1B6-538. This Air Spring provides 90% isolation at 435CPM and 97.4% at 870 CPM. Therefore, at 600 CPM the percentisolation is estimated to be 94%.

Step 3: The maximum diameter of a YI-1B6-538 is 7 inches (178 mm). Therefore, we need a 9 inch (228 mm) diameter spaceto house the Air Spring. A 9 inch (228 mm) diameter is available.Any Air Fitting Port and End Retainer Style would be acceptable.Imperial Model YI-1B6-538 is selected. Metric model YI-1B6-835 is selected. Note: this model has no internal bumper, therefore use external endstops.

*** This range is based on 100 psi; to obtain the lower limit (i.e., minimumload @ 20 psi) divide the smaller value by 5.

*** At pressures above 80 psi, usable stroke is limited. Contact your LocalRepresentative or Enidine for assistance.

† In the “Selection Chart for Vibration Isolators” section, there is a columntitled: “Approximate Isolation Percent”. The figures in this column reflectthe approximate percentage of isolation obtainable if the design height is at the center of the design height range, and the load per air spring iswithin the design load range. If the design height is above or below thedesign height range, vibration isolation may be slightly higher or lower,respectively.
