Heavy item, well packaged

The sleeve is very heavy which is expected for bronze. Packaging prevented any damage during freight shipping. Would buy again.

Perfect for high load applications

We use these in heavy industrial mixers. The bronze alloy holds up well under stress and the lubrication options are helpful.

Good value for rough stock

Product arrived as described. Surface is rough so plan for machining. Good material hardness for the price point.

Excellent casting quality

Received the sleeve for our water pump rebuild. The centrifugal casting structure is dense and uniform. Machined easily to our final tolerances.

5 FAQ

Q: What is the lead time for non-standard diameters?

A: Custom casting typically requires 3 to 4 weeks for production and quality inspection before shipping.

Q: Can this rough casting be machined to precise tolerances?

A: Yes, this centrifugal cast bronze is designed for secondary machining. We recommend standard carbide tooling for best results.

Q: Is additional oil lubrication required during operation?

A: It depends on the specific option selected. Our oil-impregnated versions are self-lubricating, while standard versions may require external lubrication.

Q: What is the maximum rotational speed this sleeve can handle?

A: Maximum speed varies by diameter and lubrication. Please contact our engineering team with your specific RPM requirements for verification.

Q: Do you provide material certification with the order?

A: Yes, Mill Test Reports (MTR) are available upon request at checkout to verify material composition.
