Using the Compression Spring Finder when Starting a New Project


When you are looking to begin a new project or prototyping a compression spring  you will need to think about how you want the compression spring to perform in your application and where you want the spring to fit.  Most likely you will not have exact measurements for this information but you will have ranges.  

Where to start?

Search Compression Springs

Find a Compression Springs

We encourage you to start with the outside diameter of your spring and the length of the spring.  


Enter OD, FL and rate range

Find My Compression Springs

In a research and design project you will most likely have an idea of how big you want the spring.  

Use the outside diameter range and free length range as a based starting point. 

For this example we are searching for a spring that is approximately ¾ inch in diameter and 4 inches long.  

Our ranges are:

OD: 0.7 - 0.8 inch

Free Length: 3.5 - 4.5 inch

176 Results

Compression Spring Finders Large Search Results


For this example we got a very large number of results, 176 in total.  Let’s assume you do not have any other requirements or know the forces needed.  I would suggest narrowing down the original search results to find a compression spring.


Enter OD, FL and rate range

Compression Springs Search Tool Narrow

We are going to narrow down our results using the same parameter, OD and FL just with narrower search ranges.

Let’s reduce the OD range first.  Our ideal is ¾ inch so we will go from 0.745 - 0.755 inch.

28 Results

Compression Spring Finders Search Results


We have narrowed down our results to 28 options, still slightly outside of the “ideal range”.  From here we can narrow down the free length results. 


Enter OD, FL and rate range

Compression Spring Search Tool Narrow Reduced Free Lenght

We are going to narrow down our results using the same parameter, OD and FL just with narrower search ranges.

Let’s reduce the FL range down to 3.75-4 inch.

This gives us 4 total results

4 Results

Compression Spring Finder Search Results Reduced Free Lenght


We have narrowed down our results to 4 options.  If you look closely at these springs you will notice that they are two of the same springs, just with different end types.  If you know what end type you are looking for you can choose the two that best match.  If you do not have a preference you can order all 4 to test. 

What do I do if I narrowed my results too far?

Let’s imagine we would like more springs for prototyping than we got in the last search.  We can go back and expand our parameters to include more options.


Enter OD, FL and rate range

Compression Spring Search Tool Increase Free Lenght

We are going to widen our results by increasing the free length range.

Let’s increase the FL range up to 3.5-4 inch.

This gives us 17 total results to prototype from.

17 Results

Compression Springs Search Results Increase Free Lenght


If you would like to choose particular springs from the 17 results the following ways to narrow down your search may be beneficial.  Since you are not using a rate to narrow down the search, try choosing springs with different rate values to test performance differences in the application.

Searching compression springs online can be done effectively this way.
