Great quality bronze

I was worried about the tolerance but these are spot on. No wobble and they seem very durable after a month of continuous use.

Excellent value for money

Bought the mixed set to test different sizes. All sizes were accurate and the material feels solid. Will buy again.

No maintenance needed

Love that I don't have to worry about oil leaking onto my project. The self-lubricating feature works as advertised.

Perfect for my 3D printer rods

These bushings fit perfectly on my 8mm smooth rods. The motion is incredibly smooth without any additional oiling. Highly recommend for DIY robotics.

Good fit, slightly tight initially

The 5mm sleeves were a bit tight on my shaft at first but loosened up after a few cycles. Works well now.

5 FAQ

Q: What is the tolerance on the inner diameter?

A: The inner diameter follows standard H7 tolerance specifications for precision fitting.

Q: Is the 3mm size strong enough for a small motor shaft?

A: Yes, provided the motor load does not exceed the maximum static load rating of 50 N/mm².

Q: Are these suitable for outdoor use in rain?

A: While bronze is corrosion-resistant, we recommend using them in dry or controlled environments to ensure maximum lifespan.

Q: Can these handle axial load as well as radial?

A: These sleeves are designed primarily for radial load. Significant axial load may reduce performance.

Q: Do I need to apply grease before installation?

A: No, these are oil-impregnated and self-lubricating. Adding external grease is not necessary.
