4pcs U Deep Groove Track Pulley Wheel Bearing,Nylon Roller Wheel Round High Carbon Steel Bearing, 4 Pcs HU-0830-10

The rollers on my screen door were cracked and we’re not working, so I replace them with these rollers. It was easy to take the old ones off and put these in. They work really well they turn really well.

Although this was a well-made product, It didn't meet my specifications for the application I was going to use it for. I needed a wider groove.

The measurements in the item description, which I was relying on for my application, were spot on and the pullies will work just fine. It would be helpful if all of your sellers who were using MM instead of inches also included inch measurements in the description.

Used these on some barn door hardware I made for a TV stand I built and they roll very smooth. I used 5/16 bolts for anyone who is using standard measurements as it was much easier to find at the big box hardware stores.

Just what I was looking for. Good quality for the price.

I am very pleased with these pulley bearings, as they appear to be of high quality. In addition, their price was amazingly low, considering that shipping was included. I ordered them on October 5, and they arrived (at my home in the USA) on October 27, well ahead of the estimated delivery date.

Watch your measurements, these are not big wheels

Two out of the four bearings in these poor bones up very hard to turn
