Help me pick a bearing

[Rated ///M]

Hey guys,

I’m trying to build some wall mounted tractor seat stools that are able to swivel to hang off the side of a low deck bar I’ve built.

I’m trying to figure out what the best bearing I can use given the cantilever force of someone sitting about 24” or so from the mounting point. So far I’m thinking a flanged sleeve bearing on a 1/2 shaft but am wondering if any of you gurus have a better idea? I don’t want to break the bank, and want to do this as economical as possible, but I don’t want them to seize or break in a season either. They will have minor exposure to the elements as I plan to lift them off and store them when not in use.

Go to tractor supply. Look at the tractor three point pins and sleeves. Cat one would work. Cheap and easy.

I have more questions than answers.
Is the triangular part made of wood or metal? The hinge part, is it metal? What does the hinge part bolt to - wall studs?
What are your capabilities - ie. Metal fabrication - cutting, welding, drilling?Wood working?
Why do you need a bearing? Your pivot point isn't rotating much.
A 1/2" grade 5 bolt or pin top and bottom, pivoting in a piece of 1/4" x
1 1/2 " bar stock would be more than sufficient to hold the weight you describe

That drawing is not the design, I was just trying to illustrate the way I was loading a bearing. These will be metal.

I’d probably go with a bronze bushing.

Thanks for the clarification.
I still say you dont need a bearing - or bushing. Steel on steel is more than sufficient for your purposes.
Make one pin a half inch longer than the other one so you can hook one then align the other to drop it on the pivot.

Don’t forget to make sure the structure can handle it. Chase the load path all the way back to the foundation.

I’ve been looking into these as well I think I have some links on my desktop.

Yup, bronze bushing

I have used Copper Pipe for bushings.

I like the first one @Garage Junkie posted. Simple pin and sleeve similar to the tractor pin concept that was mentioned.

I am thinking you don't really need a bearing but certainly no harm and would likely operate smoother. Here are some other swing away seats I bookmarked which might give you some ideas. Again, don't forget to brace the structure against turning over.
