Good value for industrial use

Solid construction and good pricing for bulk orders. One unit had a minor cosmetic scratch, but it did not affect performance. Will order again.

Durable but heavy

The sleeve is very robust and handles the pneumatic pressure well. It is slightly heavier than expected, but that likely contributes to its stability during operation.

Excellent wear resistance

After two weeks of continuous use in an anchor rod system, there is minimal signs of wear. The bronze alloy holds up much better than the standard steel ones we used previously.

Perfect fit for our drill rigs

We ordered these bronze sleeves for our Model 13 drill rigs in the coal sector. The fit is precise, and the material quality seems excellent for high-friction environments.

Reliable for harsh conditions

Our team uses these in deep shaft operations. The pneumatic compatibility is spot on, and the sleeve maintains integrity under high stress. A reliable component.

5 FAQ
