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.
