Nylon Roller Replacement

The Best Value Job on a Garage Door

If we could persuade every homeowner to do one thing to their door, it would be this.

What Rollers Do

A sectional garage door hangs on ten or so small wheels, two per section plus the top fixtures, running inside a steel track. Those wheels carry the entire weight of the door as it moves.

Most doors leave the factory with steel rollers on exposed bearings. They are inexpensive to manufacture and they are the loudest component on the door.

How They Fail

The bearing wears. The wheel develops a wobble, then stops turning freely, then stops turning at all and simply skids along the inside of the track.

That skidding is the rumble you hear through the ceiling. It is also friction the opener has to overcome on every cycle, which is why a door with dead rollers wears out openers.

Near the water there is a second factor: exposed bearings pack with salt grit, which is abrasive and accelerates the whole process.

What We Fit

Sealed nylon rollers with shielded bearings.

• Quieter, because nylon on steel is far softer than steel on steel.
• No lubrication, because the bearing is sealed.
• No grit ingress, which matters more here than inland.
• Free running, which takes drag off the opener for the rest of its life.

How to Check Your Own

Open the door and watch the rollers. A healthy one visibly spins as the door moves. A worn one slides along without turning.

Look also for wheel wobble, and listen for whether a scraping sound follows the door up the track, which points at rollers, rather than coming from one fixed point, which points at a bearing plate.

The Part We Do Ourselves

The bottom rollers sit in the bottom brackets, and those brackets are attached to the lift cables under full spring tension. Unbolting one with the springs wound is genuinely dangerous.

Middle rollers are approachable for a careful homeowner. The bottom ones are not, and that is the honest line.

What Else We Check

While the door is open we tighten hinges and track fasteners, check the bearing plates at each end of the shaft, and run a balance test with the opener disconnected.
