Mixed Bag
Most of the sleeves were perfect, but one had a minor dent on the outer edge. It still fit, but quality control could be better. The rest are working fine.

Great for Prototyping
Bought these for a prototype assembly. The finish is smooth which helps reduce friction during testing. Will order again for the final production run.

Perfect Fit for Conveyor Repair
Used these sleeves for a conveyor belt repair project. The dimensions were spot on and the stainless steel quality is excellent. No issues with installation.

Good Quality, Slightly Tight
The material feels very durable. The inner diameter was slightly tighter than my calipers suggested, but once installed it works great. Good value for money.
