Wheels Needed

[sanddrag]

What you are looking for is certainly not an easy find. Can you take 1/2" axle? What diameter do you need? Does it need to be a live or dead axle?

Does anyone know any wheels that can fit to a 5/16 shaft, metal hub, and rubber on the outer ends?

One solution might be to use these:

MSC part number: 35375278
Oil impregnated bronze bushings.
they are 3/4" OD 5/8" ID and cost $.42 each.
then just set them into the hubs on the stock wheel chair wheels and put them onto your shafts.

Just make sure your shaft is something other than bronze.
Steel would be best. You might want to help them out a bit with some light oil.

Yes, but that depends a lot on resources. Some teams don't have access to anything (mill or CNC) that would allow them to do that. If you've got the resources however, go for it. make them either keyed or able to fit a bearing of the size you want and you're good to go

The wheelchair wheels that Skyway gave us years ago have 5/16" ID bearings. If you don't have any, ask another team that's been around for awhile if they can give you some.

Over the years I've come to the realization that there are not all that many wheels with keyway (or ready for keyway) bores out there on the market. If it's something specific that you want, you'll have to make it yourself. Sometimes you'll get lucky and find something that fits what you are doing, but it is fairly common to have to manufacture a solution (at least hubs) yourself.
