Many garage doors have a spring system that is designed to create tension on the door. If you have a system like that, then you’ll either have torsion or extension springs. Here’s the difference between torsion springs and extension springs and how to know what you have.
What is a Torsion Spring?
A torsion spring works by twisting or torsion and it stores mechanical energy when it is twisted. It is designed to make the door lighter, so as not to have the full weight of it on the tracks. As the spring winds up, it will create the tension that your system needs to function properly.
What is an Extension Spring?
The extension spring can also be called a tension spring. It has helical wound coils that are wrapped tightly together to create tension. It does the same thing as a torsion spring, just in a different way. Usually, it has loops or hooks at the end and attached to other parts of the assembly.
Why Torsion Springs Are Better Than Extension Springs
There are many pros to the torsion spring system over extension springs. One of the pros to this type of part is that it typically lasts longer. It should be able to function for 15,000-20,000 garage door cycles. A cycle is a full open and close of the door.
Another reason that people like to have this part is that it allows for a more controlled motion. Extension springs tend to be jerky, causing more noise when the door is in use. Since the torsion springs have greater control, the door can open faster than if you have extension springs.
The Cons of Extension Spring
One of the reasons we suggest you get rid of your tension springs is that they usually break down faster than the torsion system. One of the reasons for this is that it is made up of more parts. The more parts that are involved, the more repairs that are needed.
Extension springs also put more strain on your opener. This can cause the entire system to wear out faster than if you have a stronger part. That means you will likely have fewer repairs overall than if you were to have a torsion spring system.
Torsion Springs Are Less Dangerous
The biggest reason that we recommend that you install torsion springs is that it reduces risks of harm to your family. In the event that an extension spring breaks, it can cause serious damage to your home or person. When the tension breaks on an extension spring, it can send the part flying. We’ve even heard of them going through windows or banging into walls.
A torsion spring system does not have this concern. You might hear a loud sound when it breaks, but there’s no way it can fly off and hurt someone.
