Can they be under mounted and still roll smoothly?

Pretty sure they can we used them for the sides but since the are ball bearing they should do the jb regardless of the mounted position.

Funny thing: that's how I used them. I don't know if they'd be rated for the same weight in that configuration, but they're working fine for me.

Not at all. These are a good product in my opinion, but even when constructed using screws they have a little wobble to them.

I do not believe they would support the claimed weight that way. There is only a rolled metal lip holding the bearings in. Like one of the other reviewers said, they are cheap and might hold light work. I would not want to stand underneath to test it though.

They can because they are thin. ..but if it's extremely round I wouldn't think that it would stick...I would say very slightly rounded yes

These will slide a little. I have them as tight as I can but still with some slippage. Still, they work fine and I'm happy with them.

Absolutely. They come out of the box slow rolling...they can be loosened or tightened to adjust the roll using an Allen (hex) wrench.

That is correct, and I am not sure of a way to easily mount them. Good luck!

They should slide with a little elbow strength. Tight squeeze. I never used screws if I remember. Good luck

Yes they are solidly attached. Unless excessive force is used I do not see them rolling of their spot.

I would say yes, and that is why I bought them. The smooth center makes for easy and quiet riding on smooth, hard surfaces. The knobs to the sides provide grip in loose surfaces. I use them mostly for gravel road riding, and like them a lot more than tires with knobs in the center.

HiI donth think i understood your question. But if you are saying would they wigle aroud after instalation, then yes they would a little even at bumps it would shake a bit but not an issue to worry about if you tighten it tightly i wont fall apart it wold hold on. So dont worry. Hopefuly thats your question.

The plates that we have are smooth. I purchased th as a gift and have seen them hung, but I can't answer with certainty regarding your question. I'm sorry.

under cover, maybe.... but they are wobbly as heck anyway... don't bother, i wouldnt buy them again.

They are secured pretty well. There is a little movement to them but not enough that they shouldn't hold in place if upright.

I wouldn't say that they "slide" but rather they "roll" and without any problem. I suspect that if you were using a regular chair and no casters involved, that there wouldn't be a problem but I haven't tried this myself.

From my experience no, as if you have to adjust them (the arms) typically you may need to tighten down the screws a bit more after moving them so they do not move or fall. The product works very well, though I would say in a fixed position that you initially set up. I occasionally move them, but not often.

You could probably find some that you could mount on the bottom but you need to keep the unit stable and level.
