Spring Selection Guide: Compression Springs Overview

Compression Spring Image

Compression Springs are open-coil helical springs that offer resistance to a compressive force applied axially. Helical compression springs are used to resist applied compression forces or to store energy in a push mode. Compression springs are the most common configuration and are most commonly used in automotive, aerospace and consumer applications. Most compression springs are a straight cylindrical spring made of round wire. Click here for compression spring specifications.

Compression Spring Types: Compression springs from a manufacturer come in a variety of types including: Conical Compression, Barrel, Hourglass and Cylindrical shapes and may have various spacing or no spacing at all between coils.  



Compression Spring Stress Levels:

  1. A compression spring that can be compressed solid without permanent set, so that an extra operation for removing set is not needed.  These springs are designed with torsional stress levels when compressed solid that do not exceed about 40 percent of the minimum tensile strength of the material.

  2. A compression spring which can be compressed solid without further permanent set after set has initially be removed.  These may be pre-set by the spring manufacturer as an added operation, or they may be pre-set later by the user prior to or during the assembly operation.  These are springs designed with torsional stress levels when compressed solid that do not exceed 60 percent of the minimum tensile strength of the material.

  3. Springs which cannot be compressed solid without some further permanent set taking place because set cannot be completely removed in advanced.  These springs involve torsional stress levels which exceed 60 percent of the minimum tensile strength of the material.  The spring manufacturer will usually advise the user of the maximum allowable spring deflection without set whenever springs are specified in this category.

Remember: It is extremely important to consider carefully the space allotted to insure that the compression spring will function properly to begin with, thereby avoiding costly design changes.
