HNBun 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.

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

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.

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

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