I am not sure if this is the correct place to ask for help for this topic, however I am sure this community knows much more the I do about manufacturing and design.
I am interested in designing a component that functions like this—
It has a very smooth rotation(360 degrees). It is small like 20 mm long and 5 mm diameter. I have no idea how its made. Does it have ball bearings? I would guess not. Does anybody know how it was made? Die casted or something else? How do they get the two parts to come together? I know very little as you can tell.
If this is the wrong place to post a question like this let me know and thanks for your help. I am at the very beginning of this creative process.
Oh also I don’t know what the other end, the hollow part looks like. But I can guess there is enough tolerance to snap in place and lock, will go in by force but can’t come out or will brake.
Or it could be more hollow in inside and there is some kind of locking device that is bit more flexible.
It looks machined from round stock.
I would guess that the smaller end is male and when pressed into the larger female portion the blind male portion deforms in some way so it cannot come back out. Too small for ball bearings.
