slip ring

by mangomeat on Fri Jun 20, 2014 8:14 am

hey guys,
I'm trying to fix some bugs on my flying coat-hanger. It's actually a coat-hanger powered by two computer fans that are remote controlled. It is hanging with counter weights on a mobile so it can move around. Now I bought your slip rings to solve the 12 volt power feeding without braking the cable through twisting it too much. I have two mini ones and one with a flange.
here some images:

I'm trying to build a hang up system to get the stress of the slip ring, but anyhow I was wondering:
Can the slip ring take any pull in direction of its axis? if so - how much? with the hanger and all the counterweight I guess the top one would have to take on 10kg of pull.
They would also hang on the cables if I hang it directly from the slip ring.
thanks! Michael

Cool project!

These slip-rings aren't designed to be load-bearing, and we don't have a manufacturer's specification for that. I would expect it would not last very long with a 10Kg axial load.

ok - thanks! already suspected that.
its actually already hard to find a bearing that works on that load...
kind regards!

You can use an automotive wheel bearing to carry the mechanical load, then fit the slip ring inside it to carry the electrical signals. Wheel bearings are conical, and can handle both radial and axial loads.
