Perfect for CNC upgrade

Replaced my old bushings with these. The motion is incredibly smooth and noise is minimal.

Exact spec needed

Hard to find the 13mm size locally. These fit perfectly on my linear rail setup.

Great for 3D printers

Using these on the Z-axis of my custom printer. No binding issues at all.

Good quality, tight fit initially

Quality seems high. They were a bit stiff out of the box but loosened up after a few cycles.

Solid construction

Heavy duty feel. The flange mounting is very stable under load.

5 FAQ

Q: Are these metric or imperial?

A: These are metric dimensions designed for metric shafts.

Q: Will this work with a soft steel shaft?

Q: What is the bolt pattern size?

A: The bolt pattern varies by shaft diameter. Please check the dimension chart for specific models.

Q: Do these require additional lubrication?

A: They come pre-lubricated, but regular maintenance is recommended for heavy use.

Q: Can I use these for vertical motion?

A: Yes, they are suitable for vertical loads provided the shaft is properly supported.
