Description

Model Description:
This is a compilation of common ball bearings. These bearings are designed to be printed in place, meaning they don't require assembly. The tolerances are adjusted to minimize play between the inner and outer rings while allowing the rolling elements to move freely. To prevent jamming between the rolling elements, there are two different variants of rolling elements guided in different grooves within the inner and outer rings.

Printing Instructions:

Since the rolling elements, depending on the size of the bearing, have a relatively small contact area on the print bed, it's important to ensure that the print bed has been properly cleaned before printing to ensure proper adhesion and avoid print defects. A glue stick may help, but in my experience, it's not necessary on a PEI plate. After printing, some force may be required to get the rolling elements to move freely. To do this, rotate the inner and outer rings against each other and check if all the rolling elements can rotate freely. They work best after some extended use or if you rotate the bearings more intensively. If the bearing doesn't loosen, it's likely that the filament needs proper calibration. If it still doesn't work, please leave a comment, and I'll adjust the tolerances accordingly.

Note: You might notice small points on the surface of the inner and outer rings. This is because the seam was changed to random to ensure smoother bearing operation and prevent the rolling elements from getting blocked by the seams.

Dimensions:

A total of 8 models or variants of the ball bearing were originally uploaded, consisting of 6 standard sizes and 2 variants in special sizes. Additionally, more bearings may be added later upon request.

Standard Sizes:

608: Outer Diameter: D=22mm, Inner Diameter: d=8mm, Width: W=7mm
609: Outer Diameter: D=24mm, Inner Diameter: d=9mm, Width: W=7mm
6902: Outer Diameter: D=28mm, Inner Diameter: d=15mm, Width: W=7mm
6000: Outer Diameter: D=26mm, Inner Diameter: d=10mm, Width: W=8mm
6001: Outer Diameter: D=28mm, Inner Diameter: d=12mm, Width: W=8mm
6002: Outer Diameter: D=32mm, Inner Diameter: d=15mm, Width: W=9mm

Special Sizes:

D50d25W10: Outer Diameter: D=50mm, Inner Diameter: d=25mm, Width: W=10mm
D25d10W7.5: Outer Diameter: D=25mm, Inner Diameter: d=10mm, Width: W=7.5mm

Note: If you require any specific dimensions, please feel free to leave a comment, and I will promptly add more models.

Added upon request:

D21d12W5: Outer Diameter: D=21mm, Inner Diameter: d=12mm, Width: W=5mm
605ZZ: Outer Diameter: D=14mm, Inner Diameter: d=5mm, Width: W=5mm
D32d20W7: Outer Diameter: D=32mm, Inner Diameter: d=20mm, Width: W=7mm
625ZZ: Outer Diameter: D=16mm, Inner Diameter: d=5mm, Width: W=5mm

Print Plates:

The print plates are named according to the bearings, making them easy to select.

The print profile consists of a total of 11 print plates.

The first print plate is a compilation of all 8 ball bearings. It is configured to print the bearings one after another, not simultaneously.
Print plates 2-9 are each for the individual ball bearings, one per print plate.
Print plate 10 contains the special sizes on one plate in case someone wants to print the fidget toy. In this case, the ball bearings need to be pressed together after printing.

Starting from the 11th print plate, there are ball bearings that were added later upon request.

If you want to create your own collection, you can also download the STL file and design your own print plate.

Enjoy printing!

Printed two of them, one I'm still not able to spin it free, the other took a bit of effort but is already working

Which one did you have problems with? If you have any questions, feel free to reach out via DM!

Printed the 608. Looks good. Will try in a few days

the print appearance is 5-star, but the functionality of the small bearing is a 3-star. I spent some time breaking the balls loose and tried working the bearing into a smooth motion, but it’s very rough motion.

@mKotek

@jaspauls Is there any chance you can model 625zz? I cannot find a model anywhere.

@jaspauls

Hello, I have designed the bearing and conducted some test prints. The contact surface of the rolling elements to the print bed is relatively small at 2 mm. However, it should work with a clean print bed. The 625ZZ ball bearing is located on print plate 14. I will send you another file privately, which has slightly smaller tolerances. This results in the inner ring running more concentrically to the outer ring. However, a certain effort must be made to free the rolling elements, which is why I have not uploaded this version. Enjoy and good luck with the ball bearing.

@mKotek

Thank you, will test them on Sunday and let you know my results.

@mKotek

Replying to @jaspauls :

Printed both, but the general one is much easier to break away the balls and good enough. Thank you.

Can you add a D21 x d12 x w5?

The designer has replied

@jaspauls

Sure, I have added the requested bearing. It is located on print plate 11. Please be especially diligent with the bed cleaning, as the rolling elements are very small. Enjoy!

@user_2381233524

Hi, would it be possible to have Bearing OD 32mm ID 20mm W 7mm ? thanks for all your hard work ...

The designer has replied

@jaspauls

Sure, I have added the requested bearing. It's on print plate 13. Out of the 4 test prints I did, only two were successfully printed, meaning you have to be extra cautious about bed adhesion, as the contact surface of the rolling bodies is extremely small. Good luck and have fun!

@user_4098515087

Can you add a 605zz and r188 ?

The designer has replied

@jaspauls

I have designed both bearings and attempted to print functional models. I own a Bambulab P1S with a 0.4 mm nozzle. Unfortunately, I was only able to successfully print a functional model for the 605ZZ bearing. The R188 bearing is simply too small to be printed with a 0.4 mm nozzle, or at least I haven't managed to do so. The very small contact area of the rolling elements prevents sufficient adhesion to the print bed, and the rolling elements themselves cannot be loosened from the inner and outer rings without destroying them. Therefore, I do not wish to publish this model here. I have added the 605ZZ model to print plate 12. Nevertheless, I will provide you with the file for the R188 in a private message so you can try to print it yourself. If you have a 0.2 mm nozzle, it might actually be feasible.

@connorw

Can you add a F684ZZ bearing

The designer has replied

@jaspauls

I designed it yesterday, but sadly I couldn't print a working model because the bearing is just too small for my 0.4mm nozzle. If you have a 0.2mm nozzle, it might work, but I don't know for sure. I will send you the model privately, as I don't want to upload something I couldn't print and verify myself.
