list of shaft hub bushing sources

i think it would be easier to ask (since this is what the forum is for) for some help. I've tried so many google searches and i come up with the same product or products unrelated whenever i put variations of this name.

basically im looking for an 11mm hex hub that fits a 4mm motor shaft.

can anyone list me places that i could go and find them?

After a few days, if you don't get a reply, bump this topic and I'll move it to the robotics section.

Hi,

These are RC car wheel hubs, I think they are 11mm at the hex and the shaft is 4mm, will check a set later today. you will see that they fix to the shaft using a pin, if your shaft does not accept a pin, there are similar types where the pin is held within the hex in which case you could probably cut a thread and use a grub screw in place of the pin. Assuming no one suggests a simpler off the shelf solution.

I've just checked and it's actually 12mm :( , the website also doesnt tell you what lengths the hubs are

these are the other alternatives:

-12mm bore -1/2" bore or 12.7mm bore - 8mm bore or 5/16" - 11.2mm hex bore (7/16") - 8mm hex bore (5/16")
