Garage Door Spring Cycle Life

The least expensive springs available rated at 10 000 life cycles or less.

Garage door spring cycle life.

The choice of the torsion spring is made according to the number of cycles thus obtained. The average garage door spring if correctly installed should last about 10 000 cycles of opening and closing. A cycle represents opening and closing the door one time. Many times we find that the wrong size.

This is dependent on the builder installing the proper size spring s. If you go in and out twice a day you re down to 7 years. The standard cycle life for a torsion spring on a garage door is 10 000 cycles. The required number of cycles is calculated by determining the average number of operating cycles per day multiplying this figure by 250 days and then multiplying the result by 10 years the useful life of a garage door.

If you only go in and out of your garage once a day that means you should expect a broken garage door spring around 14 years after the spring is first installed. As long as the only difference between the springs is the length the formula for matching cycle life is simple. It is based on winding the same number of turns per inch on both springs. Obviously the more the door is used the sooner the springs will break down.

A standard garage door spring has a design life of 20 000 cycles while tension springs should last between 5 000 to 10 000 cycles. In residential garage door springs life cycles are usually 10 000 20 000 or 30 000 cycles.
