Exact dimensions

I measured them with calipers upon arrival. The OD and ID match the listing perfectly. Great for precision machinery.

Excellent durability

Using these in a high-friction environment and they are holding up well. No signs of wear after several weeks of continuous use.

Good quality steel

The material feels solid and durable. I deducted one star because shipping took a bit longer than expected, but the product itself is great.

Great value for money

For the price, you get a good set of bushings. They work well as spacers in my assembly. Would recommend for hobbyists.

Perfect fit for my project

These sleeves fit exactly as described. I used the 9mm ID for a guide rod and the tolerance was spot on. Very happy with the quality.
