Caged Ball Bearing
by blecheimer, published
A real ball bearing needs a cage to separate the balls. So I changed my first ball bearing ( http://www.thingiverse.com/thing:56298 ) to 8 balls and added a cage.
I was a little suprised that the cage really improves the function of the bearing.
You can see the difference in this video:
If you want to print this bearing you will need a well calibrated printer. Use a layer hight of 0.1mm. After printing all parts (and the cage in particular) must be deburred perfectly.
- Print the parts (flip inner_c_2.stl and cage.stl)
- deburr them (!)
- load the balls
- insert the cage
- snap-on the inner part
- let it roll
