I have been looking into possibly building my own cargo bike (inspired by the xyz cargo bike). That said, I am interested in possibly modifying the design - including how the steerable wheels are attached to the frame.
When I research how others have solved attaching these wheels to the frame, I often see them attached using rod end bearings that seem to have a fairly significant axial load on them. (To be clear, I don't think the xyz cargo bikes use this technique).
My questions are:
Am I misunderstanding what kind of bearing they are using here? They look like rod end bearings to me, but I am a rank amateur when it comes to this kind of stuff.
If these ARE rod end bearings, is it OK to apply this kind of an axial load to them?
