Extension spring 2,5x22,5x237,5x80 - ČSN 026030

Tension springs are springs used for applications that are loaded with tension.
Tension springs have a hook at each end to accept the load. Some models designed for specific applications have plates with holes instead of hooks.
Tension springs are usually made from materials such as hard drawn steel wire, spring steel, piano wire and stainless steel wire. Different materials are recommended for each tension spring application, so the application and operating environment must be considered when selecting the spring material.
