This means I did my job well and this part works. Thank you very much.

Considering the limitations of 3D printing, including the difficulty of printing a sphere, I decided to design my own bearing. I designed the most popular 608 bearing with dimensions of 8x22x7. As you know, it's a very small bearing but widely used in many amateur projects. The main issue with these printed and commercially available bearings was the excessive play.

My proposal is a single-row, crossed-roller bearing. Due to its design, the crossed roller bearing can handle both radial loads (perpendicular to the axis of rotation) and axial loads (along the axis of rotation), as well as combinations of both.

The bearing is printed in parts and assembled into a whole. There is no print in place.

How to assemble?

Apply a small amount of grease to the center ring and paste the individual rollers. The grease will hold it in place during the folding process. Then squeeze them with the other two pieces. Look at the assembly drawing.

Successful printing!

Printed in PETG (Tecbears) on a P1S. Everything fits and works, although two spools melted. However, the bearing doesn't run perfectly smoothly yet. Very well suited for slow, stable storage. I will also print this in ABS to see if it runs more smoothly. Thank you for your work and for sharing

Thank you very much for your comment. I spent a lot of time choosing the tolerances. My goal was 'almost zero tolerance'. In other bearings, there is either too much play or they are made of such thin walls that they are soft. I admit that I tested it myself only on PLA (Colorfil). Please check if the seam is set to random. And I think I will start making more bearings in this concept because there are none like this and there is interest. I use also Klübersynth MR 96-31 as a lubricant. Best regards."

Replying to @RedRavenPL :

As I already wrote, the bearing will be very well suited for higher loads, even laterally. The seam was already randomly placed. I also have some Klüber Synth grease lying around somewhere. I first found the silicone grease for the coffee machine ;-) But first the ABS test. The tolerances of the parts are indeed very tight. A magnificent feat of engineering! Regards Tom

Replying to @user_3013541971 :

The Bambu ABS result is superior The material feels better due to its increased hardness The bearing runs more smoothly I have also replicated a few spare spools A test with Geeetech ABS+ is underway I am unfamiliar with this material Let's see what transpires In any case it deserves five stars
