Extension Springs
A tension spring is a type of coil spring that is used to receive a load in the pulling direction. Among springs, it is widely used after compression springs and is often used for stainless steel and hard steel wires for springs. It is common to use hooks at both ends. For springs that are used in a wide range from commonly used items such as bicycle stands and seismic isolation devices, select the appropriate one depending on the load and required tension.
