Do not forget that the shaft is the other half of a bearing. It must also be in good condition or it will wear out your replacement bearing in a big hurry.

Don't forget to smooth out the marks left by shaft collar set screws before trying to slide a bearing over them -ouch!

We do not have shafting, but a length of standard cold-drawn round from your local steel supply warehouse should work just fine in most cases.
