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

These are made from a durable metal that glide appropriately. They are easy to screw in and they are uniform in size - they weren't uneven once I screwed them into the platform that I put under my washer. The low profile works well in basements, laundry rooms or other places with hard, flat floors. While they would glide on wood flooring, I think they would leave marks on the wood. These are not a good substitute for living room or other formal furniture.

Well made

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.

I got these to make two stationary room dividers mobile. They run smoothly on concrete. They don't get stuck and are multidirectional.

Very good quality very fair price worked very well for my application.

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!

Great product! Good quality!

seemed to be a good product. worked well for my use under a qwik jack.

Only needed 8 for my QuickJack modification. But found them so useful that I installed them on anything that I'd like to slide around my shop.

These are good quality and work well. They are loud when they roll though.

For moving heavy stuff! These transfer balls are great!

Item as described! Works well.!
