Swing away fabrication (4 Viewers)

[Hyphagon]

Hi All,

I have a swing away tyre carrier on my 80. Not sure what brand it is. It's currently only got a tyre on the right hand side and I want to build my own bike rack for the left hand side. It's got a solid post already on the bar ready to mount another arm. Only thing it doesn't look like most other swing aways as there is no thread and castle nut on the end, I guess gravity just keeps it on. Not knowing the brand I can't find any bearing/seal/outer cylinder kits. The axle stub is 25mm or 1" diameter.

My thinking:
Buy 2x bearings and a seal (1" id) and get a steel tube that matches the outside diameter. Weld one end closed (top) pack full of grease and slide bearing in with another tube to act as a spacer.

My questions:
Do I get cone bearings or normal skateboard type (not sure their proper name!).
Is there a special steel tube I can get has the correct ID to match with bearings (maybe for building trailers...) if so what would it be called to help search for it.

Or any other better ideas......

Thanks

That shaft is designed for a bushing. Drill the side of the outer housing and install a grease zerk and put grease in it to keep it smooth.
If you would like to keep it on there other than gravity, drill and tap the center of the end of the shaft and place a stud and nut or just a bolt from the top down, on the outside with a sealing washer and Nylock nut to hold it on when you're upside down.

Keep it greased and it will last forever. The ones with bearings typically seize up due to rust in the bearings. Bushings are designed to be greased and may have a slight amount more play, but will last forever as long as there is lube in them. The pivot pressure is on what appears to be the bronze plate at the bottom.

Many farm implements are designed without bearings because they can tolerate dirty conditions as long as they are kept full of grease to not let water in. If water does get in, the tolerances are not so tight that they rust the two parts together like a bearings will do.

Have a look on ruff stuff specialties website. They sell lots of fabrication parts including a nice kit for swing away bumper arms. I used it to make my two swing arms.

I also added a vertical bike rack to mine. Still got to fit a gas strut to it but here’s some pics if you need some ideas:
