16 PCS 1/2 Inch Roller Ball Transfer Bearing, Flange Mounted Carbon Steel Round Ball Transfer Unit, Universal Rotation Ball Casters for Conveyor, Roller Stand, Transmission, Load Capacity 22 lbs

I put these underneath a craft item that I wanted to have moving around. They work fabulous they're easy to install and the quality is good

I'm using them for a lazy susan. All the bearings roll well. They're not too heavy. I was a little surprised they didn't come with screws. I don't know about longevity but my initial impression is that they are a good purchase.

Great addition to a base to help furniture move better across smooth surface.Do not recommend using on uneven hard surfaces, like rough concrete, wheels will deform quickly.

These are perfect! Very durable. I’ve had over a ton in weight on them and they worked just as smoothly as if there were o weight on them

Look well made. Changed project and haven't used them

Happy with the product. Vinyl roller bearings for smooth operation.

I made some boxes for the back of my truck I put 10 rollers on each side my Box is in the back of my truck slide in-and-out like butter. They are definitely worth your money they hold the weight.

Made two boards about 8 x 26 inches and mounts rollers on. Put boards under 60 inch mower deck and lowered on to boards. Made the job of sliding the deck out the side so much easier. Worked great for my application.
