How To Replace The Rollers On A uPVC Patio Sliding Door - Schlegel Patio Rollers

All patio / sliding doors have one thing in common. They all use patio rollers (wheels) to slide upon. The patio rollers are mounted on the bottom of door, and sit on top of a track which allow the door to slide back and forth. The first signs of wear or damage to the rollers is the door not sliding easily or taking extra force to open and close it. The most common reason for this is wear and tear, (years of sliding back and forth) but there are other factors that can shorten the life span of the rollers.

Another big factor in shortening the lifespan of the rollers is dirt and pet hair. The track area of the patio sliding door is very prone to the collection of muck and dirt. This dirt and muck in turn get drawn into the bearings of the rollers causing them to seize up. Dog hair is the worst offender.

Maintenance For Your Patio Rollers

To ensure a long life for your patio door rollers follow these simple steps:

  • With a sweeping brush, brush any dirt or pet hair out of the track area. Do this on a regular basis
  • Use WD-40, 3-in-1 oil or similar to lubricate the rollers. Choose the spray can with the straw. This is particularly useful for getting in to the rollers at the bottom of the door, without having to take the door down to apply it.

Maintenance Tips for Patio Door Rollers

Replacing The Rollers On Your uPVC Patio / Sliding Door

If it takes excessive force to slide your door open and closed then the rollers are most likely worn and need replacing.

To replace the rollers on a uPVC patio / sliding door, you will need to lift the door off the track. To lift the door off the track you must first remove any anti lift blocks and cover strips that prevent the door from being lifted. See the video below to see how you remove these anti lift blocks and cover strips.

You will need to lay the door down on the ground to remove the rollers. You will need to put down cardboard or timber on the ground to protect the door from scratches etc. Alternatively if you have a set of folding saw horses you can lay the door on these.

* You will need two people minimum to lift the door off the track *

  • Lift your door straight up. While lifting up, pull out the bottom of the door. The door should now be free from the track.
  • Lay the door down on its one of its edges. Get the second person to hold the door while you change the roller.
  • The patio rollers will be fixed to the door with two screws.
  • Remove the screws and remove the old roller.
  • Fit the new roller making sure the end with the adjustment screw is facing out. Re-fit the screws.
  • Repeat for the other roller.
  • Stand the door back up. Lifting the door, put the top into the frame first followed by the bottom. The door should be on the track now.
  • Slide the door across approx 1/4 of an inch from the closed position. Using the door frame as a guide, look at the gap between the door and frame. We want the gap to be equal top and bottom. This is important for getting the door closing and locking properly. If the gap is bigger on the top than the bottom, adjust up the back roller (furthest from the door handle). If the gap is bigger on the bottom than the top, adjust up front roller (closest to the door handle).
  • Using a Philips screwdriver, put the screwdriver in the gap between the track and the door. You will feel the adjustment screw. Tighten the screw to raise up the roller. Loosen the screw to drop down the roller.
  • When you have the door gap equal. Close the door fully and test it is locking correctly.
