When replacing compression springs one wants a good compression spring replacement it is most important to prioritize the compression spring dimensions for your application and narrow it down from there. The spring finder at The Spring Store is set up to search compression springs online,  the spring finder prioritizes the outside diameter, length and rate of the compression spring you are looking for. If any of the other dimensions are high priority you can click on “search more fields” and use these fields to narrow the search.  


When replacing a compression spring it is most important to make sure the compression spring will fit properly in your application and will perform adequately for your application.  The outside diameter and free length will determine the fit of the spring and the “rate” will determine the function of the spring.

 

Input Compression Spring Dimensions

 If you do not know the rate of your spring you can use the Spring Creator to determine that value.  Simply enter in your dimensions and hit calculate.

Compression Spring Table Wide Inputs

Spring fits in a 0.500 inch diameter hole and needs to be approximately 2 inches long. The force (rate) is unknown


*Account for Tolerances


*Range of Search starts wide and narrows with each added search criteria.  This first search brought back too many results, 502

*Range of search - Start with a wide range of search criteria and narrow it down from there.  You can see in the above example that I started with a free length range of 1.5-2.5 inches and an outside diameter of 0.450-0.485 inches since I have some room in my design.  This brought me back 502 possible results, much too large of a range to search through.  You should narrow this down to a smaller range, we would always recommend narrowing one search field down and then the other.  Below I will show examples of how to narrow down the results.


*Always account for tolerances in your spring. If you need a compression spring to fit inside a space or over a shaft allow for 0.005 - 0.025 of an inch of tolerance on the compression spring.  In the example above this spring needs to fit inside a 0.500 diameter hole so we are searching for outside diameters up to 0.485

In this search we kept the OD range consistent and narrowed down the Free Length range. 


By narrowing down the free length in my search for a compression spring, I simplified the results from 502 to 153, still too high.  From here I will tighten up the outside diameter search criteria

Narrow the second dimension

In this search we narrowed the OD range down to 0.475-0.485 and left the free length at 1.75-2 inches.  


By narrowing down the outside diameter range I have reduced my results to 99 options.  We do not recommend trying to navigate 99 options so I would take another look at my application for my next priority.

Compression Spring Search Solid Height

Questions to Ask Yourself…..

Is your spring fitting over a shaft? 

Do you know the force profile required? 

Does your application require a particular material type such as stainless steel?

Do you know the wire thickness?

Do you have a max solid height requirement?  


For this example we will assume I need stainless steel and I have a max solid height of 0.500 inch.
