Extension Spring Tech
Extension springs are also known as tension springs. They are close wound linear springs because there is initial tension keeping the coils together as to be pulled apart. Learn about their dimensions and how they work.
Torsional Spring Tech
Torsional springs are also known as torsion springs. They are close wound rotational springs with legs on the ends because they deflect radially under torque. Learn about their dimensions, specifications, and how they work.
Conical Spring Tech
Conical springs are also known as tapered springs. They are non-linear compression springs for they are open wound but have variable coil diameters. Learn about their dimensions, specifications, and how they work.
Spring Rate
Spring rate is the proportional amount of force per one unit of distance traveled. This is what makes compression and extension springs linear. Learn about the formulas, calculations, and how spring rate works.
Spring Design
Spring design is very extensive since there are several subjects to learn about per spring type. Below you can find general design information for the three main spring types; such as formulas and explanations on how everything works.

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 Table
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.
Extension Spring Finder
Shopping for springs on a mobile device?
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
