Tension Spring: Everything You Need to Know

What is a Tension Spring?

A tension spring (also known as an extension spring) is a mechanical component designed to operate under tensile stress. Unlike compression springs that push back when compressed, tension springs pull components together, returning them to their original position after being stretched.

Where Are Tension Springs Used?

Tension springs are widely used across many sectors and everyday applications, such as:

• Garage doors
• Drum brakes
• Household appliances (e.g., washing machines, vacuum cleaners)
• Industrial machinery
• Mechanical toys

Wherever there is a need for automatic return to position, a tension spring is often the solution.

How Does It Work?

These springs are designed with loops or hooks at both ends. When pulled apart, the spring stretches and stores mechanical energy. Once the pulling force is released, the spring returns to its natural length, drawing the connected elements back together.

How to Choose the Right Tension Spring?

Several factors must be considered when selecting a tension spring:

• Free length
• Wire diameter
• Outer diameter
• Required pulling force
• End type or loop shape
• Material (galvanized steel, stainless steel, etc.)
