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.

Excellent Durability

We are using these in a high-moisture environment and there is zero signs of rust after three months. Highly recommend for outdoor machinery applications.
