Yarlung 20 Pack 1 Inch Roller Ball Transfer Bearings, Carbon Steel Swivel Ball Casters Two-Hole Screw Mounted Ball Transfer Unit for Roller Stand, Conveyor, Transmission

Very good quality very fair priceworked very well for my application.

Great product! Good quality!

These are constructed from a two piece stamped steel form. Then a steel bearing is sandwiched between. Obviously not made for heavy loads. However using many of them together greatly enhances their load capability. There is no lubrication so it's just the ability of the steel bearing to spin within its formed cavity.

Very strong, working great

I screwed some of these to a 2x4x4' and clamped the 2x4 to a portable work station thing and use it as a roller support when I'm cutting 4x8 sheets of material by myself. They are a snap to install - just 2 screws and they provide a super smooth omni-directional glide so you can move the panel in any direction with ease. WAY cheaper than buying another roller that'll just tip over at a critical moment!

They work exactly as you would expect them to and made moving a storage chest that I built a breeze. Would purchase these again if the need arose.

Product sent was in good condition, as described and fits my needs. Great shipping and packing condition.

I got these to make a tool carousel. The balls roll smoothly and the backside is enclosed. If you need to make a surface that slides easily on another surface, try these out.I would not use these with the ball directly on the floor, I think it would pick up too much dirt.
