sliding glass door rollers

I have some sliding doors that are around 15 years old. The rollers are all pretty much shot. I think they are the 81-261 model rollers, but not sure. Also not sure if there is another wheel that would be an upgrade.

One thing to note... My doors are stacked... some of them are 5 doors wide and I must have 15+ doors that slide all over the house. The tracks are quite large, and fill up with water in the winter durring a storm. I think this contributes to the wear on the roller bearings significantly.

I've attached some pictures of my roller. The dimensions are very slightly different than the 81-261 model... but it doesn't seem like so much that it would make a difference.

Thanks in advance... really want some sliding doors that don't have to be lifted every time I want to open them!!!

Without remeasuring mine for exact number, I purchased two of the 82-261 items and unfortunately they do not fit. :(

Mine is about 1/8" shorter, 1/32" less wide, and about the same length. The 1/8" taller in the 82-261 is what makes it not work.

Do you have anything that might work? If I had the right tools, I could just shave off 1/8", but I don't.

Those look almost identical to mine. Will give them a try.

Thanks!
