These bearings are espacially designed for 3D-printing. These bearings don't use regular balls like other bearings but it uses specially designed for 3D-printing balls. This insures the most supple 3D-printable bearings with the least amount of play. The bearing prints in only one piece, fully assembled. You may have to wreck the balls a little lose after it has printed because the tolerances are very small. For the best result you can lubricate it with some grease like WD40 for example. Hope you like it and can use it in your project. (results can depend on printer settings and type of 3D printer used).

dimensions bearings:
small bearing: inner diameter = 12 mm
outer diameter = 40 mm
height = 12 mm

i would be smart if you updated the "thing details" with the dimensions of the bearing like inner and outer width.

Otherwise outstanding job!

Thanks for the tip, will do that and thank you!

It looks like it's welded together when slicing with slic3r:


I pressed "Split" button in Slic3r and welds are gone.

Very nice Frol, glad to hear this.

I added pictures of the bearing being sliced and printed

Indeed i can see but I use cura engine to slice it and it is perfect. Will post picture
