Sliding door becoming harder to move

[1594mac]

Good evening any advice please

Large sliding door on shed is becoming harder to slide shut its approx 15ft x15ft box section and tin. Whats the best way to get it running better? Lubrication? Remove and replace the rollers? Any pointers would be great

Is there adjustment?
Has it simply swelled a bit in hot weather?

There's usually height adjustment on the top rollers. If you have a guide bar in the botom it may need raising off this. Spray oil on the top rollers, the adjusting nuts & leave for a few days as they are usually seized up! Then raise by a few turns.

I don't think so its just been harder to open and close for a while I will get a look at it see if there is a way of adjustment

My Big timber door on barn bows in the sun then seizes . I think its the peg that stops it swinging at the bottom that it binds
Bin threatening to make a roller / guide wheel but hasn't happened yet

What size tracking and rollers have you got ? The smaller size isn't really up to the job, and doesn't last long.

I haven't a clue unfortunately

get up and apply decent quantity of grease inside the track where the wheels run all the way along , as they do dry out. presuming you have it adjusted correctly

I d wondered about loads of sticky stuff ??
Best loads of lube ? Will shite stick to it ??

Aerosol spray grease / chain grease

blue tits like to sleep in the end of one of my sliding tracks . Every now and again bad things happen. Oopps

Are the rollers visible?
If not could be a broken roller up there. Had that before on a similar sized door.

Sometimes the nylon rollers dry out with lack of lubrication and then bind up. You then end up with a flat spot on them as they wont rotate as you slide the door and the problem will keep making itself worse as the roller diameter decreases and the door drops.

Is it catching on the floor/floor rail. Maybe a daft question but ours do that as the building settles. We seem to have to keep on adjusting the up now and again. Usually the rollers aren't a problem if oiled now and again.

I had similler size box And tin door
First get up in a man basket or ladder to have a way up
I had similar and oiled the track and roller axles with a oil can with a pipe on but it started sticking a year or so latter and the adjusting bolt whent thro a tin chassis between the roller wheels amd it split open letting the door mount bolt drop so i had to remove rollers jut Couldnt het new so i welded up ttje old ones
Hope this helps
