Torsion Vs Extension Springs – A Head-To-Head Comparison

By  | 

When selecting the appropriate spring type for your application, many factors must be considered, including load requirements, space restrictions and material properties. Spring index is another key consideration as it determines coil tightness, strength and manufacturability.

Torsion springs can be tailored to meet specific requirements by altering leg style, material and wire diameter settings. Furthermore, they’re easy to install and operate.

Introduces the two spring types

Torsion springs are an integral component of garage doors, as well as numerous other items and situations. From clothespins and door hinges to paper cutters and paper shredders – you’ll likely come across them every day!

These sturdy springs are often constructed using oil-tempered or high carbon steels, but other alloys may also be utilized. Furthermore, additional corrosion-prevention measures like pre-galvanised coatings may be added for additional anticorrosive protection.

Torsion spring leg length is determined by taking into account its total coil and wire diameter, along with its free angle of deflection. To select an appropriate spring for your application, it’s essential that you understand these factors – the higher the free angle is, the more degrees of deflection it can handle.

Where Torsion Springs Shine

Torsion springs are perfect for applications requiring rotational force. These helical-wound springs store mechanical energy by twisting, and can even be designed with customized leg configurations to fulfill specific purposes.

Torsion springs have flexible characteristics that make them useful across industries, from automotive to aerospace. Understanding key dimensional properties – such as the angle between spring legs and mean diameter according to mandrel size – is essential in selecting an appropriate torsion spring for any given application.

Torsion spring legs may be configured in straight, hinged, or other custom forms to meet individual requirements. Their coils may also be open or closed – this determines whether a torsion spring has left-handed (clockwise) or right-handed wind; coil count also has an important bearing on spring rate, deflection capacity, and load capacity.

Applications for Extension Springs

Extension springs are widely utilized in garage doors. They store energy and exert a pull force that helps open and close it smoothly.

When shopping for an extension spring, key characteristics to keep in mind include its initial tension, length and spring rate. Spring rate measures how much force is necessary to travel or extend a certain distance unit and is typically expressed in pounds/in of extension.

Make sure your custom extension spring has hook or loop ends for ease of attachment and reattachment, with loop ends providing more robust anchoring solutions for your application. Finally, consider both diameter and angular relationships of its ends before purchasing custom extension springs.

Comparing Key Characteristics

As well as price, durability and performance when choosing the perfect spring, other factors must also be taken into account when selecting one. For instance, in extreme environments it might be important to choose spring materials capable of withstanding high temperatures.

If necessary, selecting a specific diameter and length may be required to ensure the spring fits correctly. While this task should be fairly simple if replacing residential doors, industrial and commercial applications often present greater challenges.

Selecting the Best Spring for Your Needs

Torsion springs may cost more upfront, but their lifecycle far outlives extension springs–research has indicated as many as 15,000 or 20,000 lift cycles for them! They also keep doors in better balance and are safer to use than extension springs which may cause jerking during opening and closing processes.

Material used to construct springs plays an integral role in its durability, so considering load requirements, environmental conditions and other relevant considerations when selecting an ideal technical spring is critical for successful application.

For instance, if your springs will be exposed to high temperatures on an ongoing basis, selecting a nickel-chrome or inconel alloy might be ideal in these harsh conditions. Stainless steel also provides great hardness and resistance levels that could benefit many applications.
