6 Pcs - 1" Roller Ball Transfer Bearing,Flange Mounted Carbon Steel Round Ball Transfer Unit Universal Rotation Ball Casters for Conveyor,Roller Stand,Transmission, Load 400 lbs

I like the price

These were bought for a wooden platform that is 7 ft x 4 ft. They work a little too well. Even with 300lbs of wood and 100+ lbs of plants, they roll smoothly and effortlessly. I will absolutely purchase these again for future projects.

Let's all say it together, "You get what you pay for!" These rollers are no different. When furniture grade ball caster sell for $12 apiece, you should probably keep your expectations in check when you pay $15 for 6 on Amazon. I purchased these to use as casters for a small plywood storage box. Of the six rollers I received, four worked okay. They are noisy (lubricating them is not an option when using them as a furniture caster unless you want oil or grease oozing out all over your carpet!) and the rolling action is rather herky jerky.

Very noisy. Not a smooth ride

Seem to be made well. Roll easy.

The rollers did the job exactly as I had planned. Couldn’t be better.

I needed a very short roller, these worked perfect.

I returned these to Amazon. The quality was extremely bad. The roller balls do not roll smoothly. They stick and grind like they have gravel in them instead of bearings.
