Garage Door Roller Replacement in Rexdale

The nylon tire itself needs none; spraying it or the track only collects dust that grinds the wheel. The hinge knuckles and stems where they turn benefit from a light coat of garage door lubricant once or twice a year, worked in by running the door. The ball bearings themselves are lubricated only where the roller's own maker calls for it, since some nylon rollers should not be greased there. Rollers with sealed bearings come greased from the factory and need only a wipe and a look.

It depends on what they are made of and how often the door moves. Builder-grade plastic wheels with no bearings often show wear after only a few years. Steel and nylon rollers with seven to thirteen ball bearings are typically rated for ten to fifteen thousand cycles, roughly the life of a torsion spring, which for many households means seven to ten years. Sealed-bearing nylon rollers are rated far higher. A door used many times a day, or one living with salt and slush, shortens all of those.

One roller can be changed on its own, and sometimes that is the sensible stopgap after a wheel breaks. The better result comes from a full set, because the other wheels have done the same number of cycles and are close behind, and mixing new with old, or nylon with steel, leaves the door running unevenly and sounding different on each side. A matched set also lets the technician set every top fixture and check every hinge in one pass.
