16Pcs 1” Roller Ball Transfer Bearings, 360º Rotation Universal Ball Casters, 400Lbs Carbon Steel Round Ball Transfer Unit for Conveyor, Roller Stand, Transmission, Furniture

These are GREAT. I bought them to put on a solid wood double size trundle bed that was on sliders. These are a game changer. I used all of them on the bottom of the trundle to make sure there was adequate support. They roll so nicely and barely raised the height as compared to the sliders. Absolutely no complaints.

I needed better rollers for a trundle bed These were small but strong, and easy to mount. They worked well, but unfortunately I couldn’t keep using because of my soft wooden floors. I would highly recommend over concrete, like in a shop or garage. They roll easily in any direction and had a high weight capacity.

Have not used yet but don't see any problems with product should work fine

So handy, easy to screw in or glue on! Makes furniture and lightweight things so much easier to move around. Recommend!

I bought 16 of these and mounted them onto a piece of wood. I put a self-adhesive rubber pad on the bottom to keep the mini transfer table in place. So, what is it for? Well, I have summer tires and winter tires which are mounted on their own wheels. With this thing I made, it is a piece of cake to change out the tire sets. I can push the wheel up flush to the hub and rotate the wheel to align the lug nut holes (my lug nuts have a male end). I don't have to try to hold the wheel in place with one hand (very difficult) and try to thread a lug nut with the other.

These worked well for my project but they're noisy and squeaky. They cannot be greased or oiled because it's a ball and the grease would get all over your floor/carpet.

Great product for the money. I used them underneath drawers in the back of my truck. They glide easy and are very sturdy

Details matter, especially in an installation. Price is good less than two bucks apiece. I bought the 1" rollers. Out of the box, they roll very nicely. 400 lbs? I am not so sure. In my application these rollers should have been fine. I made drawers that fit into a big box in the back of my suv. The drawers did not slide well at all, so I thought putting these rollers through the box from the bottom would make it much better. It did not. The description says 2" wide. I Drilled a test hole but they were smaller than described.... 2 inch was the only hole saw that I had that would work. Had I known the true size around 1 7/8" I would have had that size... I got them where they needed to be, but they do not roll well at al. I put 5 rollers for less than 21" spread out evenly. Weight was no more than 300 lbs total. I am stuck with them but not happy. I would not buy these. This is my second review... first was flagged for some reason.... not sure why. Even had pics.... Only reason I tried again is because I want people to know about these rollers so they can make an educated choice.

Used for homemade truck roll out (bed slide) Work great.

Unsure yet but will be Moving Heavier Car equipment on concrete floors.
