The ASI Compression Springs stock range has its origins nearly 75 years ago, developed collaboratively by Automatic Spring and John While & Son. This catalogue was created to provide engineers with a dependable, standardised range of compression springs for design, maintenance, and production use.

Over the decades, this range has remained largely unchanged, reflecting the robustness of the original designs and their widespread adoption. These catalogue spring sizes have been referenced in engineering drawings and production assemblies worldwide, becoming a recognised and trusted standard across many industries.

Following the liquidation of these original manufacturers approximately 30 years ago, we believed this established range should be preserved rather than lost. As an Australian-owned and operated business, we continue to manufacture and supply this compression spring range in Australia, maintaining its availability, consistency, and reliability for today’s engineers while upholding a long-standing local manufacturing tradition.

Custom Compression Springs

Where the standard catalogue range is not suitable, custom-designed compression springs can be manufactured to meet specific dimensional, load, material, and service life requirements.
