Torsion Springs For Garage Door

In June 1921, C.G. Johnson invented the first torsion spring for the overhead garage door. This spring's ingenious design consisted of a coil wrapped around a shaft, with one end fixed and the other end attached to a cable. When the door is opened, the spring is twisted, storing energy. When the door is closed, the spring unwinds, providing the power to lift the door. Torsion springs are still used in most overhead garage doors today, and they come in a variety of sizes and strengths to accommodate different door sizes and weights.

Torsion springs are made from high-carbon steel, which is heat-treated to give it strength and durability. The springs are typically coated with a zinc-rich primer and then painted to protect them from corrosion. Torsion springs are available in a variety of sizes, with the most common sizes being 1-1/4 inches, 1-1/2 inches, and 2 inches in diameter. The length of the spring will vary depending on the size and weight of the door. Torsion springs are also available in different strengths, with the most common strengths being 100, 125, and 150 pound-feet.

When selecting a torsion spring for a garage door, it is important to consider the size and weight of the door, as well as the desired opening and closing speed. It is also important to select a spring that is strong enough to lift the door, but not so strong that it causes the door to open or close too quickly. If you are unsure about which size or strength of spring to choose, it is best to consult with a professional garage door installer.

Torsion springs are an important part of an overhead garage door system. They provide the power to lift and lower the door, and they also help to control the door's speed and movement. If you are experiencing problems with your garage door, it is important to have the torsion springs checked by a professional.

In addition to their use in garage doors, torsion springs are also used in a variety of other applications, including:

Automotive suspensions
Industrial machinery
Agricultural equipment

Torsion springs are a versatile and reliable type of spring, and they are used in a wide variety of applications.

Here are some additional tips for choosing and using torsion springs for garage doors:

Choose a spring that is the correct size and strength for your door. A spring that is too small or weak will not be able to lift the door, while a spring that is too large or strong will cause the door to open or close too quickly. If you are unsure about which size or strength of spring to choose, consult with a professional garage door installer. Inspect your torsion springs regularly for signs of wear or damage. If you see any cracks, rust, or other damage, replace the springs immediately. Lubricate your torsion springs regularly with a silicone-based lubricant. This will help to prevent the springs from squeaking and will also extend their lifespan. If you are experiencing problems with your garage door, have the torsion springs checked by a professional. The springs may need to be adjusted, replaced, or lubricated.
