A simple two-piece 608-size bearing designed to be completely 3D printed.
Unlike traditional printed bearings that use printed balls or rollers, this design uses a sliding-contact mechanism between the inner and outer parts. It is simple to print, easy to assemble and works well without lubrication.
Specifications
Inner diameter: 8 mm
Outer diameter: 22 mm
Width: 8 mm
2 printed parts
No balls or rollers
No supports required
Designed for PLA
Works without lubrication
The design is intentionally simple: print it as a single piece and start using it immediately.
This bearing is fully print-in-place, with no assembly required after printing. It can be used without lubrication for normal operation. Adding a small amount of suitable lubricant is optional and can further improve smoothness and reduce friction.
A small amount of suitable lubricant can be added if desired, but it is not necessary for normal operation.
Printing
Recommended starting settings:
PLA
0.20 mm layer height
2–3 walls
4% infill
Dimensional accuracy and the final fit can vary depending on the printer, filament and print settings.
This is the first model in a planned series of two-piece printed bearings based on common bearing dimensions.
