uxcell Ball Transfer Bearing Unit 12mm 17Lbs Nylon Bolt-Fixing Type for Transmission Pack of 6

I used these casters on my dining chairs to make them easier to move. They’re definitely heavy and really good quality and roll easily. If I had any critique at all, it’s that I kind of wish they also came in black so I didn’t have to spray paint them but besides that, they’re great.

Works, but not as smoothly as the all metal ones I have used.

Excelente

I purchased these a while ago and right out of the box, you could tell that the build quality of these ball transfers are garbage. The bearings themselves where not even spherical so you could feel the dips as you rolled them around. I wouldn't recommend buying this products. Just a waste of money.

My biggest complaint is why does it come in a set of 6? Now I have 2 random leftovers.

Product is nice. We use to move center coffee table. It's fully metal. Just one thing find that when move It's make sound. I think technically need pvc ring between ball & body for smooth functioning. Otherwise it's good.

Used these to make rolling platforms for storing boxes in the dark recesses of the closet under the stairs. They work well, have good weight capacity and roll easily.
