Increasing Torsion Spring Life:

One of the most common questions our sales staff receives is how to increase the life of torsion springs. The answer is to convert a spring with a larger wire size and match the inch pounds per turn of the original spring. This will result in a spring that is capable of more maximum turns, and therefore, a higher cycle life than your original spring.

Spring Growth:

Spring growth can be easily determined by multiplying the number of required turns by the wire size.

Example: a .250 wire spring requiring 8 turns will grow approximately 2 inches after it has been wound. (.250″ wire size x 8 turns = 2″ spring growth)

Determining the Amount of High Lift:

High lift is measured as the distance from the top of a closed door to the bottom of the horizontal track.

Proper Handling of Springs:

It is important to prevent any nicks or scrapes to the wire when handling springs. Any small scrape or nick could result in premature spring failure.

Cycle Life of SSC Springs:

Torsion springs that are engineered by SSC are designed for a minimum of 10,000 cycles.

Figuring Door Weight:

To figure the weight of a properly functioning door, divide the total inch pounds per turn of the existing springs, by the multiplier of the cable drum.

Ordering Springs

No matter what kind of springs you order, there are a few important aspects for you to consider. Here is everything you need to order springs.

Ordering Torsion Springs:

When ordering torsion springs, there are 4 specific items you will need to know in order to get the correct replacement spring. Those items are: the wire size, inside diameter of the spring, length of the spring, and the wind of the spring (right or left wound).

Determining Wire Size

A spring’s wire size can be determined by using a caliper, micrometer, or wire gauge. If none of these tools are available, simply measure ten coils of wire to the nearest 1/16th of an inch, and refer to the Spring Wire Chart. The spring must be tightly compressed, with no gaps. Still unsure how to properly measure a spring? Register for Solutions Education and view the ‘How to Measure a Spring’ video tutorial.

Determining Inside Diameter (ID)

First, measure the inside diameter to the nearest 1/16th of an inch. For springs with cones inserted, the cone will likely have a manufacturer’s name (OHD, Raynor, etc.) which will give you a clue toward the proper identity. The chart, available here, shows the most common IDs used by various manufacturers. If no manufacturer’s name is evident, usually a part number on the cone will indicate the ID.

  • Part No.: 134 or 175 = 1 3/4″ ID
  • Part No.: 258 or 263 = 2 5/8″ ID
  • Part No.: 375 or 334 = 3 3/4″ ID
Measuring the Length of a Spring

First, measure the spring length in an unwound state. The spring must be tightly compressed, with no gaps. In the case of a distorted or broken spring, simply count the total number of coils and multiply by the wire size.

  • 120 coils x .250 wire = 30″
  • 120 coils x .375 wire = 45″
Which Wind

One of the most commonly misunderstood facts about the wind of a spring and the placement of the spring on the door, SPRING WIND, also known as wound, refers to the direction the wire is coiled to make the spring. The wind is helpful to know because it helps determine the direction the spring will uncoil as the door moves up and down. Cones will have threads that match the spring’s wind.

A Left-Hand Wound spring is mounted on the right side of the door and a Right-Hand Wound spring on the left. There are exceptions to this rule but this is recommended for engineering.

Helpful trick: Make an ‘O’ with your index finger and thumb. Using the tip of your finger as the end of the wire, follow the direction down your finger and it will give you the direction the spring is coiled.

Find which Wind is correct for the job

Ordering Extension Springs:

When ordering extension springs you can use 2 different methods to determine the correct size of replacement springs.

  1. Determine wire size
  2. Measure the inside diameter to the nearest 1/32″
  3. Determine the spring length (do not include loops in this measurement)
  4. Specify type of ends (double loops, single loops, or clips)
  5. Specify type of door (sectional, one piece or taylor sectional)
    1. Example: .177 – 1 3/32″ ID – 25″
  1. Measure spring length
  2. Determine amount of stretch (amount of stretch is half the door height)
  3. Provide the door weight
  4. Specify type of ends (double loops, single loops, or clips)
  5. Specify type of door (sectional, one piece or taylor sectional)
    1. Example: 25″ – 42″ 150 lbs.
