Though we try to offer a broad range of standard springs please note that most spring applications require a custom design. Please contact our engineering department or use our design software to develop your application. For more information on our capabilities for extension springs or to submit specifications select the view details link.
(1,762) Selection Extension Springs are organized in order of increasing diameter and wire size. Note that in each category the spring rate decreases as the length increases.
After identifying the proper outside diameter of the spring needed, select a range for wire diameter and free length. The broader the range of values selected the more options will be offered.
Maximum Load & Extension The maximum loads and extended lengths are provided as a precautionary guide. They are based on a stress of 35% of tensile which is good for most applications. Even though most of these springs could be used beyond the listed lengths in light applications, there is a higher probability that the spring will deform or the loop ...
