Nope, no bearings. Basically it's a bushing type. Fromhttp://www.diygokarts.com/chopper-plans/rake-forks.html:
If you look at Fig 2, you'll see the hole that's drilled in the forks. It's 1/2". Then when I made the frame, the fork to frame tube is welded to that. You can see that by itself in fig 1 from
http://www.diygokarts.com/chopper-plans/frame-design.html .
That little neck tube thing (heck, i forget what you call it) is tube, not pipe, and has an inside diameter of just over 1/2". I want to say it's 3/4" tube, but don't hold me to that. I'll have to go out to the garage and find out later.
Then, a 1/2" bolt is used to complete the connection, in figs 6-7 on page
http://www.diygokarts.com/chopper-plans/rake-forks.html
It works pretty well, too. That's the same method that is used to make the go kart spindles.
Thanks for posting this. I'll update the info on the site later today to make it more clear.
