The writeup was not clear on the axle size (they're 10mm, I needed 8), so I had to make adapters (fortunately there is stock tubing available for that), but once I got these installed on my FiL's walker, they worked much better than the old wheels, as not only did the brakes work better, these wheels slide less on the floors.

The photos and clearly state the inside diameter is 10mm.It's a 8mm inside diameter so it will not fit your axel.These bearings are 10mm inside diameter that I have in the photo to compare with these bearings.https://www.amazon.com/gp/product/B072LBYHNK/ref=od_aui_detailpages00?ie=UTF8&psc=1You can see in the photo they are 2mm smaller.

I liked the fact that you delivered them to me quickly. My husband had to do some adjusting to make them fit my Lumex Rollator but he was able to make the fit. I need this rollator to walk a mile each day (since I have multiple sclerosis which causes balance and tripping issues for me). I wear the wheels out so quickly and I got tired of purchasing new rollators when all I needed was new wheels. Thank you very much.

I bought the wheels for my Wife's walker as the other ones were pealing rubber off. These wheels are better because of the roller barrings and the rubber much better material although it would be better is the rubber was wider, but it works great on blacktop and cement.

These wheels are not 8". they are closer to 7 3/4" which didn't work for me because the brakes would not reach. Might not matter as front wheels, but my chair has four 8" wheels, and the backs have parking brakes. The old wheels are worn down which doesnt allow the brake to make good contact with the wheel. Same problem when the new wheels are short. Otherwise, no problem with the seller. They came right away.

Your product information was woefully inadequate. You did not list the hub width of this part nor show a picture that would have indicated hub width. This wheel was too narrow but I had to use it anyway, by adding a stack of washers to each side to make it fit. The result was unsatisfactory and I will have to buy again to get the CORRECT wheel, before this one gives up. I'm not happy.

These wheels are just what I needed for replacing old wheels on my rollator walker. The wheels are 8 inches and very sturdy. The wheels are very easy to install also. I use them for the rear wheels on my rollator.

I don't know what this is.
