Chain Drive – That is the most common type of garage door opener. As the name would imply, it utilizes a chain to push/pull the trolley that moves your garage door either up or down. This type of drive is very affordable and considered very reliable, as well. The downside is that they can be noisier, thus making them best suited for detached garages.
Screw Drive – This garage door opener type uses a threaded steel rod which rotates to move the trolley as it opens and closes your garage door. Since there are fewer parts to a screw drive opener, it will require less maintenance over the opener’s lifetime. They are also the fastest when it comes to opening a garage door (10 – 12 inches/per second – as opposed to 6- to 8-inches per second, which is the standard). For safety purposes, all garage door openers close doors at 7 inches/second. The downside is that it is usually noisier than a belt drive.
Jackshaft Opener – These garage door openers are different from other systems since they mount on the wall next to your garage door. It uses a 24-v DC motor to drive pulleys and cables, which turn the torsion bar and raise the garage door. This type of garage door opener is both quiet and reliable. That also allows for additional ceiling storage space. However, these openers are more expensive than most other opener types.
Direct Drive Opener – Since these openers only use one moving part (the motor), they are claimed to be the quietest of all of the garage door types. These openers developed and manufactured in Germany, and its motor (not a trolley) will travel along a stationary chain, which embedded in a rail that installed overhead. The moving motor linked to the door by a J-arm. They cost the same as belt driven openers and usually come with lifetime warranties.
Other types of garage door openers include DC-Powered openers that can possess variable speed capability that will enable soft-start and soft-stop technology. The battery backup can also integrate within the units. DC motors that have brushes have a shorter life expectancy than AC motors. However, brushless DC motors have the same life expectancy.
