Size variance
The 8mm ones were a bit tight on my shaft. Had to ream them out slightly. Otherwise okay.

Good quality copper
Material feels solid. Had to press fit them carefully as they are slightly soft, but once installed they work well.

Excellent wear resistance
Using these in a linear motion project. No binding issues and the oil impregnation lasts a long time.

Perfect for my 3D printer
These bushings fit perfectly on my 5mm rods. The self-lubricating feature works great and reduces noise significantly.
5 FAQ
Q: Can these be cut to custom lengths?
A: Yes, you can cut them with a fine hacksaw or tubing cutter, but ensure the edges are deburred after cutting.
Q: Are these suitable for outdoor use?
A: Copper is resistant to corrosion, but for harsh outdoor environments, we recommend additional protective coating or housing.
Q: What shaft tolerance do you recommend?
A: We recommend a shaft tolerance of g6 or h7 for optimal sliding fit without excessive play.
Q: Do I need to add oil regularly?
A: No, these are oil-impregnated during manufacturing. They are self-lubricating for most standard applications.
Q: What is the maximum load capacity?
A: Load capacity depends on the specific dimensions and speed. Generally suitable for light to medium loads in linear applications.
