Tension Springs

Tension springs are springs used for applications that receive a tensile load. Close-wound springs are the standard type since they save space and make effective use of initial tension. Tension springs have a load-receiving hook on both ends. Some models designed for specific applications have plates with holes in them instead of hooks. Tension springs are typically made of 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 should be considered when choosing the spring material. For example, general-purpose springs are made from materials such as hard drawn steel wire and piano wire, while heat-resistant springs are made from materials such as stainless steel wire.
