Sliding Door Roller Ø24 × 8.5 mm (Griffwerk)

I designed this roller after the original roller of my Griffwerk sliding door broke.
The complete replacement part would have cost around 200 € – so I designed, printed, and successfully installed the roller myself.
It has been working flawlessly ever since and runs smoothly and precisely in the rail again.

I am making this model available for free here so that other users can also repair their sliding doors instead of having to replace the entire system.

Technical Details:

• Outer Diameter: 24 mm
• Total Height: 8.5 mm
• Circumferential Groove: U-shaped, centered, serves as a running track in the door rail
• Central Bore: recessed for ball bearing reception
  • upper step: Ø 16 mm × 7.5 mm depth
  • lower step: Ø 15 mm × 1 mm depth
• Recommended Material: PETG (robust, slightly flexible)
• Recommended Bearing: suitable bearing with internal thread or press fit Ø 15 – 16 mm

Print Settings (Bambu Lab / Prusa / Anycubic):

• Layer Height: 0.2 mm
• Perimeters: 4–6
• Infill: 40–60 % (Gyroid or Cubic)
• Material: PETG or ASA
• Support Structures: not required
• Orientation: flat (one flat side on the print bed)
• Cooling: medium (30–50 %)
• Print Temperature: 240–250 °C (PETG)

Assembly Note:

After printing, insert the ball bearing or bearing bush flush into the recess.
The roller can then be reinserted directly into the door mechanism.
A drop of lubricant (e.g., silicone oil) ensures even smoother operation.

Result:

The sliding door is running perfectly again, the repair was significantly cheaper, and the spare part holds up.
I hope this model also helps others to avoid unnecessary costs and replace defective parts themselves.
