16 Pcs 1" Roller Ball Transfer Bearings, 400 Lb Capacity

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.

I'm well satisfied with this product. I will be ordering more.

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.

Easy install but they are hella noisy! Was gonna use them for an indoors projects but just way too loud for my first idea. Don't want them to go to waste so found an outdoors/ garage use for a few of them - added them to the bottom of an umbrella weighted stand. Have not tried rolling them with full weight yet but they did ok with just the weight of the wood. Not very smooth rolling even just in my hand spinning the ball but it works for now. Didn't notice their noise as much outside either. Fingers crossed they hold up & can actually handle high weight amounts. Jan 2024 - Well! I tried them on 2 other projects & they failed miserably on both. Hella hard to roll on garage floor with not even 100 or 150 pounds on a set of 4! Very disappointing! Guess I'll try them on something lightweight which is not what I wanted them for.

Watch the weight limits. If you put these on furniture or a rolling cabinet, watch the weight limit! If you exceed the weight limit, these bearings self-destruct. The inner bearings become deformed and start flying out of the assembly, and they are then defective and useless. This is not a defect, it is that the consumer must pay attention to weight limits. When I put them on a cabinet, the cabinet was empty. All seemed fine. Then I overloaded the cabinet and that is why they failed. Watch the weight limits!

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

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