Rollers and Other Small Garage Door Parts08/22/2014 Back To Blog
Garage door rollers may just be small parts of large moving equipment, but paying attention to these little things will surely keep the big thing in order. A standard two-car overhead door could weigh up to 400 pounds, depending on the material used, but it is possible to open it with one hand. How can this be possible? It is because of the work of the smaller parts, namely the garage door springs, pulleys, rollers and bearings.
Importance of Rollers
The heavy weight of the garage door is lifted by the springs, and the rollers are the ones that keep things in line and reduce the remaining frictional load. Rollers can either be metal or nylon wheels. These two groups are also divided in different quality grades. Higher quality rollers feature ball bearings and even maintenance-free sealed ones. Replacing rollers can improve your door’s operation. This is a good move if yours are already worn out. Rollers should match the wheel size, the shaft’s length and diameter. Make sure the rollers are also positioned at the access point of the track so that they can be replaced individually, without having to tear the entire door down.
Dirty garage door track, sticky bearings and worn out rollers can add up to the friction that can even lead to the door’s break down. These parts are all inspected during garage door maintenance. The track is also given enough attention. It must be free from debris and properly aligned. Even small pieces of dirt can prevent the roller from rolling smoothly. If there are obstructions here, added loan will be taken by the garage door opener or the user’s arms. Some rollers could operate without the need to lubricate the track, while others require a dry lube. It is important not to use just any oil-based product in the track for this could just attract dust. Bolts should be kept tight because loose mounting leads to misalignment.
