Frequently Asked Questions

 

What is the purpose of a tension spring?

The purpose of a tension spring is to store energy and create resistance by pulling two components together. It operates under tensile force, extending when pulled and returning to its original shape when the force is released, ensuring a secure and controlled connection.

 

Do tension springs wear out?

Yes, tension springs can wear out over time due to constant stretching and relaxing, which may cause them to lose their elasticity. Factors such as excessive load, fatigue, and exposure to harsh environments can contribute to the deterioration of the spring's performance.

 

What is the difference between coil spring and tension spring?

A coil spring is a general term for any spring made from coiled wire, used to store energy and resist force in various applications, such as compression, tension, or torsion. A tension spring, specifically, is designed to withstand pulling forces and stretch to store energy, typically used in applications where components need to be pulled apart, like in garage doors or trampolines.
