Conveyor Rollers, 1" Heavy-Duty Support Roller Bearings, 20 PCS Roller Balls for Smooth 360-Degree Rotation for Rolling Furniture, Pickup Truck Bed, Workshops and Garage, Heavy Equipment.

These are perfect, I built a bed slide with these, check YouTube they work

These are super for table-saw outfeed tables or for roller benchtops to help support heavy stock, or for a thousand other uses. Very handy to have some of these on-hand in the garage - I was surprised at how many different uses that I've been able to identify for them, and I've been happy overall with their performance and quality. No problems or issues - seems to be a great product. Recommended!

Unless you are using this to slide carry on bags across, these casters are extremely lightweight. Put any sort of load on them and they lock up.

They roll like cubes. And they’re loud.

I thought these would do the job in my workshop. They just cannot carry the weight. I plan on using them for smaller projects and I am sure they will perform as expected. The quality of the casters is fine and the only thing to beware of is the weight issue limitation. I had read the comments and decided to try these casters anyhow. Next time I will listen. No reflection on the seller or the product itself. I like them but not for the original design I planned to use them for. I would definitely order them again.

I am building a lazy susan for my welding table and I am using these conveyor rollers to make the lazy susan. It will not just rotate, but also move side to side. This should make welding projects a lot easier to get to the spot I need them. These are stout and can hold a lot of weight. They are easy to attach with the base they are on having 2 holes for attachments via screws. The are smooth and should last a long time. I will buy these again for other projects.

The rollers make excellent in-feed and out-feed table rollers for saws, mill, routers etc. The rollers are very smooth and provide easy material positioning on machine tool tables.

These roller balls are good for projects in my woodshop. I have used them for many years. This pack of them appear to be well made and will be very useful.
