How to Assemble 3D Printed Ball Bearings

- Editing is a little rough, but it gets the idea cross. I am using these as apart of a cycloidal drive I am making, but I don't want to break the bank on just bearings alone so I wanted to see if I could make my own. Thankfully I can use these, because the equivalent bearings on McMaster Carr are $35 for the smaller one and $155 for the larger one. Both sides can be shielded with a slight modification, but I will leave that up to you. Hope this helps!

I just printed off a few of these to test with and try out for some projects i've got in mind. For assembling, I used a magnetized security torx screwdriver (just what i had) and it works PERFECTLY. You can pick up a BB with it, and since it's "security", it has a hole in the center, which keeps the BB centered on the bit... then i use the driver to press it into the bearing pieces. No spatula/spudger necessary... it works so well and so quickly!
I have never owned a torx screwdriver before you are right! Those look like they would be ideal! Thanks for pointing that out! I hope the bearings work well for you! If they feel a little bit loose and have too much play just increase the temperature that you are printing them at until you get a good fit.
@@Dangineering The key is that the "security" version has a hole in the center, so the BB will sit cradled in that portion. :D THank you again!
This is pretty fantastic, and good job on the solidworks model. I'm designing a low-cost SCARA arm for easy DIY and I think this will be part of it!
Thanks! I'm glad others are finding use for them. I look forward to seeing progress on the low-cost SCARA arm.
Nice!
I also like that you record the sound even if you choose not to talk. Only question I have is why you did not put in the balls in sequence and instead spread it around first.
Thanks for sharing 👍🏼
Awesome work on these bearings, can you make a video showing how to assemble the triple bearings?
If I some extra time I will make a little video, but until then its pretty much the same as assembling a single row bearing by starting on one side and building your way to the other side.
Any tips on printing these. I've tried 3 different "Horizontal Expansion" in Cura because mine are way to tight. Cant get all the balls in. I'm printing at 0.12 layer height. How much clean up do you do? I've tried to sand down the seam and get rid of any strings. Thanks.
I am actually a little surprised you are having so many issues. They printed well on my Ender, but always had to sand the seam. On my prusa I have never had any problems and essentially do no post print clean up on them. My suggestion to you would be to measure the internal dimensions of the part you print and compare it to the value you should getting, this will tell you if your printer is inaccurate in one dimensions., Have you done a test print to ensure that your prints are dimensionally accurate?
If you don't mind my asking... at 3:15, what were you using to lubricate?
Oh, I found your answer further down - silicone grease.
Hey!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! please answer, that rubber ring at 1:08, where did you get it?
What type of grease did you use? Thanks!
100% silicone grease or lubricant will work best.
And for your next trick: Linear recurclating ball bearings!
What size are the balls?
They are simply 4.5 mm BB's: www.amazon.com/dp/B000HKKY7C/ref=twister_B081ZSPJ9Z?_encoding=UTF8&psc=1
Do you have these large bearings for sale?
I do not have them for sale, but the link to the STL files is in the description and you can 3D print them for a very low cost!
Hello. Do you have any tutorial about how to make this bearing?
check the description or my other videos.
@@Dangineering i already checked the description and your other videos and there is no tutorial about how to make the bearing in Solidworks
@@santiagogarciarestrepo6600 click on the printables link. You can download the parametric solidworks file through there.
how do you assemble a triple one?
With a metric shit load of patience
@@Dangineering Hey!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! please answer, that rubber ring at 1:08, where did you get it?
@@Dangineering ikr, i assembled, i was about to build a quadruple one, but ended with just three, it was a hell, because the bearing was embeded in my design, anyway. i need to know about that rubber ring.pleaaase
Could use a magnet or two
I’ve designed a much better bearing design I’ll upload later
