Key features

 

Industries we serve

Coil Springs Direct serves various industries with our premium tension springs, including:

 

Understanding Tension Springs in Dynamic Systems

Tension springs are essential components in systems where controlled resistance and return force are required. They store energy when extended and release it to pull components back into their original position, making them ideal for applications like garage doors, trampolines and mechanical levers. Their reliability and versatility have made them a staple in both light and heavy-duty industries, offering consistent tension performance over time.

What Is a Spring Tensioner and When Is It Used?

A spring tensioner is a device that maintains consistent tension in a system by adjusting or absorbing movement over time. These are often paired with tension springs in conveyor belts, pulleys and industrial machinery where slack or vibration can impact performance. Using a spring tensioner alongside a correctly rated tension spring helps prevent wear, reduces maintenance needs and ensures smoother operation under varying loads.

Using a Tension Spring with Bolts for Custom Assemblies

When space or design requires a more secure setup, a tension spring with bolts can offer added stability and precision. These configurations are commonly used in adjustable assemblies, such as gates, hatches or equipment covers, where a bolted connection allows for a custom-fit solution. Whether you're working with standard or bespoke measurements, integrating bolts can increase anchoring strength without compromising the flexibility tension springs are known for.

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.
