A basic 7 ball ball bearing I modelled to be used as a component in other assemblies that require rotational movement. Balls are spaced with a cage that has two halves and can be held together using m2 screws. I also added an additional but optional bearing cover incase you may want to protect the balls from foreign objects if the need be.
I made this as a reusable component to use in future projects and was made using fusion360. The cage was made by cutting through hollow shells of slightly larger balls so they can fit around the regular ball.
Note: NOT print in place
The holders are now combined with on cage half for easier printing. The whole thing has been upscaled to fit in an approx. 87mm diameter circle. A screw hole has been added for the covers to keep them assembled.
For assembly
The inner and outer and outer groves are put together first, with the inner placed slightly to the side to allow the balls fit in.
All SEVEN balls are then put in the space between the two grooves, after which they are then evenly spaced by slightly adjusting each ball to a space in-between the two grooves.
Then the cages are put around the balls, one cage on each side. You may want to place the bottom cage down before positioning the balls in the previous step.
When the two cages are surrounded the equally spaced balls, You can then screw them together using 5mm m2 screws (you'll need seven of them), starting from the cage that doesnt have the screw holders to the one that does (The small round rings attached to one of the cages)
The bearing should be fully functional now, and if you want to use the bearing covers, just place the directly in the center of the bearing, making sure the square peg fits properly with the other side's square hole, the using an 8mm m3 screw to screw them together.
