Needs Break-in

Had some friction at first, smoothed out after a few hours of operation. Just be patient during installation.

Perfect Fit

These bushings fit my 3D printer shaft perfectly. No wobble and smooth movement right out of the box.

Good Quality

Solid bronze feel, slightly tight fit initially but loosened up after some use. Good value for the price.

5 FAQ

Q: Are they corrosion resistant?

A: Bronze offers good resistance to oxidation, but we recommend avoiding harsh chemical environments.

Q: What is the tolerance level for these bushings?

A: Standard H7/g6 tolerance is applied to ensure a secure press fit with standard shafts.

Q: Do I need to add oil during installation?

A: No, these are self-lubricating. The oil is impregnated within the material and releases during operation.

Q: Can these handle high speeds?

A: They are suitable for moderate speeds up to 2000 RPM depending on load and lubrication conditions.

Q: How should I install these sleeves?

A: Press fit installation is recommended. Ensure the housing is clean and deburred before insertion.
