Reliable components

Used these for a custom 3D printer upgrade. The smooth surface reduces friction significantly. Will definitely buy again when I need more.

Solid industrial grade

Very hard steel, needed a proper reamer to get the final fit just right, but that is expected for this hardness level. Works great as a spacer.

Perfect fit for my lathe project

These bushings are exactly what I needed. The tolerance is spot on, and the steel feels very durable. Installation was smooth without any forcing required.

Great value for money

You get four different sizes which is very convenient for prototyping. The metal quality is superior to other brands I have tried at this price point.

Excellent wear resistance

I've been running these in a high-friction application for three weeks now, and there is zero sign of wear. Highly recommend for heavy-duty machinery.

Good quality, fast shipping

Solid construction and good finish. I used the 8mm size for a repair on my garden tiller. Only giving 4 stars because the packaging was a bit loose, but the parts were undamaged.

A: Each sleeve in this assorted pack has a standard length of 20mm. If you require custom lengths, please contact our sales team.

Q: Are these bushings suitable for outdoor use in rainy conditions?

A: Currently, this SKU is sold only as an assorted set. However, we do offer bulk packs of single sizes under different product listings on our store page.
