Improved Version:

The cylindrical roller bearings perform better than deep groove ball bearings when it comes to force absorption (see picture 2). They are also easier to print and can be customized for various applications. With the right material — for example, Igus filament — they can even be made mold-free, making them suitable for use in the food industry.

The bearings are available with tolerances of 0.05 mm (super fine), 0.1 mm, and 0.2 mm, depending on customer requirements.
However, the print quality strongly depends on printer calibration — even the best design won’t deliver good results on a poorly calibrated printer.

This was a small side project, by the way.
