Not all garage door parts are created equal. Below we've outlined the best combination of garage door parts depending on the spring system. Each part can be made of a variety of materials, so we've rounded up the best of the best. Each of these garage door parts is a piece of the whole system and can affect the noise level and long term operation of your garage door.
Extension System
Pulley: A solid cast iron pulley has a sealed bearing and often lasts twice as long as a riveted pulley and won’t split as it is made from a single piece of iron.
Extension spring: The shackle clip spring isn’t part of the coil as the clip is bent around the end of the spring, meaning it won’t be as susceptible to wear and tear and ultimately break off, as is possible with a double loop spring.
Rollers: Nylon rollers are quiet as they roll along the track. They have sealed bearings so they’ll never need lubrication.
Operating cables: Aircraft quality cables have almost 3x the amount of wires with 7 wires per strand and 19 strands per cable, increasing the durability and strength of the cables.
Torsion System
Center bearing: Sealed steel center bearings are the same donut shaped piece of steel with a second piece of steel placed within the donut, supported by small sealed bearings for independent movement. The fluid movement of the second piece of steel eliminates friction on the tube for smoother operation.
Torsion spring: Powder coated springs will not rust or corrode because of the coating that protects them, leading to a longer lasting, quieter system.
Rollers: Nylon rollers are quiet as they roll along the track. They have sealed bearings so they’ll never need lubrication.
Operating cables: Aircraft quality cables have almost 3x the amount of wires with 7 wires per strand and 19 strands per cable, increasing the durability and strength of the cables.
