Frequently Asked Questions

What is a SPEC extension spring used for?

A SPEC extension spring, like the 302 stainless steel machine hook type, is used to provide a pulling force in industrial applications such as machinery, automation, and material handling. It stores energy when extended and returns to its original length, making it ideal for counterbalancing, tensioning, and return mechanisms.

How to select the right extension spring for an application?

To select the right extension spring, consider free length, wire diameter, outer diameter, and material. For example, the SPEC 302 stainless steel spring with 0.031 in wire diameter suits light-duty tension. Ensure the spring's maximum extended length and load capacity match your mechanism's requirements to avoid over-extension.
