9/64” Outer Diameter Extension Springs

Compression Spring Finder

Shopping for springs on a mobile device?

Find and buy stock compression springs in two simple steps using Spring Finder. This easy to use search engine makes it easy to find and buy the stock spring you need.

The following simple steps will get you started:

Enter Your Inputs
Select Your Spring(s)

Step 1.) Enter Your Compression Spring’s Dimensions

If you are interested in buying a stock compression spring, you must know what you require your spring to do and where it will have to fit. Spring Finder is divided into a basic search and an advanced search. You can choose to search in English (inches and pounds) or Metric (millimeters and Newtons) units of measurement. The fields provided in the finder each correspond to a particular spring specification.

In the basic search, you can enter:

outer diameter
free length
spring rate

Each dimension has two input boxes so you can select a range. These are the limitations you want to set so that the search can provide results within those tolerances.

For the advanced search, you must select “Search More Fields”. Here you can enter:

load
deflection
total coils
solid height
inner diameter
wire diameter
material type

Once you’ve entered your spring’s specifications, click “Search”.

Step 2.) Select Your Springs

After you have clicked “Search” on the Spring Finder, you will be directed to a page of results. The number of results you will get depends on the dimensions and ranges you entered. You can choose to view from fourteen to seventy results in one page and you can choose whether to view them in a table/list or side by side as products in grid format. Besides choosing the quantity of results you want to view, you can also organize them based on the specification of your choosing.

The following are the specifications you can select to organize your search:

Product Name
Price

Spring Finder Results in Grid View

After sorting the products in the order of your choosing, you can start looking through the list to decide which spring will work best. You can find the spring based on the maximum load or the maximum deflection. When you find the spring that meets your load and travel requirements, you can then check whether the spring rate meets your working loads. Furthermore, you can check pricing at different quantities by clicking on the Quick View icon.

If you still need help deciding select your springs and “Add to Compare” by clicking on the icon of two circles joined together on each product. This is to be able to compare them side by side in a more efficient manner. To enter the Compare Products page, find the link at the top of the page. Then, just quickly add them to your cart to complete your order. If you need further assistance finding your springs, you may contact our team of experts to help you out. Our engineers can help answer your questions and assist you in finding the correct spring for your application.

Give us a call for assistance!

Find and buy stock extension springs in two easy steps using Spring Finder. This simple tool makes finding the stock tension spring you need a fast and productive task. Search through over 4,000 designs off the shelf.

The following simple steps will get you started:

Enter Your Inputs
Select Your Spring(s)

Step 1.) Enter Your Extension Spring’s Dimensions

When searching for a stock extension spring, you base your search on its parameters and tolerances. We do have thousands of springs in stock but, most likely, you will find springs similar to yours, not exact replicas. Spring Finder will allow you to search for your springs in both english and metric units. Initially, it gives you three parameters to search your spring by but gives you the opportunity to expand it into a more advanced search where you have more parameters to choose from.

In the basic search, you can enter:

outer diameter
length inside hooks
spring rate

Next to each dimension, you will see two input boxes where you can enter your max. and min. tolerances for that specific parameter.

To access the parameters in the advanced search, click on “Search More Fields” where the following dimensions will be available:

load
deflection (travel required)
initial tension
wire diameter
material type

The fields are not mandatory so you can choose whatever dimension you feel needed and click “Search” once you have done so.

Step 2 - Find Your Springs

After clicking “Search” on the Finder, you will be directed to a page of results. These results are displayed in a table/list as default but you can select to view them in a grid format where they will be shown side to side. The amount of results you get will depend on how many dimensions you entered and how tight or loose the tolerances are. Based on how many results you generate, you can also choose to show from fourteen to seventy products per page.

These are the specifications you can organize your extension springs by:

Part Number
Price
Outer Diameter
Length Inside Hooks

Rate
Max. Load
Max. Deflection (Max. Travel Required)
Initial Tension

Wire Diameter
Total Coils
Inner Diameter

After you have figured out how you want to display the results of your Spring Finder search, you can begin finding potential products based on the suggested max load and deflection/travel, as well as the spring rate. Select all of your potential springs and “Add to Compare”. Scroll to the top of the page once you have done so and click on “Compare Products” where they will be displayed side to side. Check out pricing at different quantities by clicking on “Quick View” or click on the part number to be directed to the product details page.
