Print in place 6000 Ball Bearing

Print-in-Place 6000 Ball Bearing (0.20 mm Tolerance)

I designed this bearing because many of the 3D-printed bearings I tested were either too loose and unstable or too stiff to rotate smoothly. This is my own design, which aims to provide a good balance between stability and ease of movement.

 

The bearing was test-printed with clearances ranging from 0.15 mm to 0.25 mm. After testing, I found that a 0.20 mm tolerance provided the best combination of smooth rotation and minimal play.

 

This is a fully print-in-place standard 6000 ball bearing that requires no supports and prints in approximately 20 minutes.

Specifications

• Bearing type: 6000 ball bearing
• Print-in-place design
• No supports required
• Tolerance: 0.20 mm
• Print time: ~20 minutes
• 3 grams of filament
• Tested on a Bambu Lab P2S
• Material: PLA Basic
• Tested at:
  • 0.12 mm layer height
  • 0.08 mm layer height

Notes

This bearing is ideal for prototyping and testing mechanical systems that require a 6000 bearing. While it performs well for 3D-printed applications, I would still recommend using a metal 6000 bearing for projects where long-term durability, high loads, or sustained use are important.

 

If there is enough interest, I can also upload versions with alternative tolerances for different printers and materials.

 

Enjoy, and feel free to share any projects you build with it!

Standard 6000 Bearing Dimensions

• Inner diameter: 10 mm
• Outer diameter: 26 mm
• Width: 8 mm

These dimensions match the standard 6000 bearing size, making it suitable as a prototype replacement in designs that use conventional 6000 bearings.
