Keel Roller Bracket Design

I have a trailer build thread running through which I have received some sound advice. I am now at the stage of making brackets for keel rollers. I have 10" V-rollers for the keel but cannot get galvanised, stainless or zinc plated pins for them.

Please can anyone advise or send pictures of keel roller brackets and details of pin fitment through the roller and the supporting metal brackets. In particular should the central roller pin be an interference fit and the pin turn in the bracket through some form of bearing or should the roller rotate on the pin?

Many thanks

Roller should rotate on the pin and thereby provide a much larger bearing surface. Do not use hot galvanized pins, the surface is very rough. use zinc plated mild steel.

Could just get some stainless round bar cut and drill a hole in each end to take a washer and split pin?

This is in the US, but it looks like there's not much to design (for the pins, anyway):

Poke around on the site; should be able to find pretty much anything you're looking for. Most stuff can be fabbed pretty easily, I think. Easier to buy it though.

Thank you all for the advice. I now have a clear idea of what I need to manufacture. The website in US was very clear. The difficulty I have is getting stuff shipped to the Middle East.
I shall get cracking with the roller brackets and pins.
