Problems with other 3D printed bearings like “no cage” or “too loose”?
Just print these, they are easy to print and after a few test prints, you have a good fit.
Dimensions
- Outer Diameter: 22 mm
- Inner Diameter: 8 mm
- Height: 7 mm
Tolerances
To achieve higher tolerances, I used the same techniques as Matvey Kukuy in his Ultimate 608 Bearing with Calibration Kit V2. Basically you have to optimize two variables, in this case:
- Horizontal Tolerances (HT)
- Vertical Tolerances (VT)
The values can be found in the Filename (608-BEARING-HT-VT). For the optimization, a binary search algorithm can be used. Please refer for this to Matveys Kit, I got it from his site, so I don't want to take the praise for it.
If the calculation is too tiresome for you, I (and ChatGPT ;) ) wrote a graphical program for this specific use case. The executable and source code can be found on GitHub.
Print Instructions
- Print one at a time (otherwise smaller defects might form and increase tolerances)
- I printed mine with 0.1 mm layer height, higher might also work
If you want other sizes, just request them, I have an easy creation workflow now.
