Ok, thank you. Again the problem is, we cant get such things here very easely. So, I think I need to find someone who goes on a trip to the Netherlands and want to bring it along for me.
But it is a smart thing.
@Robert OB 33/48 I used the same part for my swing gate, essentially it's an axle from a small trailer. It has a 1.5" solid steel pin, two cartridge bearings and an outer race with a 2.25" outer diameter. I think it's rated for 2000lbs. If you visit atozfabrication.com they have it listed under builder parts. I would think something similar would be available over there, maybe from some place that sells small utility trailers?
