Tension Springs

Tension springs are another name for extension springs ; but unlike extension springs, they don’t have pitch in between their coils.

How different is it from compression springs?

In comparison to compression springs , tension springs function oppositely. While compression springs aim to compress, these tension springs are designed to either extend or to pull. As a result, their springs are spread open.

Why?

Tension springs resist pulling forces. This creates a sling back effect when the force is removed, so it returns to its original shape. This makes them ideal components for equipment and machines that require lifting heavy objects or dispersing particular loads.

How do tension springs differ from one another?

Tension springs differ on:

• Length
• Thickness
• Shape
• Hook

All of which are dependent on their purpose. Nevertheless, almost all tension springs have hooks on their ends. This helps in facilitating their extension properties. Some of the most common types of tension spring hook types are: cross-over and machine hooks. Nevertheless, you will also find certain tension springs with no hooks.

What is the disadvantage of a tension spring?

The hook of the tension spring is its weakest part. This is also the easiest to bend or break off, especially when it gets pulled. So, some prefer tension spring designs with no hooks at all. This is then screwed into the ends via bolts that act as its fasteners.
