Perfect for High Temp Molds

Good Quality Control

Dimensions were spot on according to our calipers. One sleeve had a minor scratch but did not affect performance. Would order again.

Excellent Wear Resistance

Running for 6 months now with no signs of wear. The graphite impregnation really works to reduce friction without external oil.

5 FAQ

Q: Do I need to add oil during installation?

A: No, these are self-lubricating due to the graphite plugs. However, a light coat of oil during initial assembly can help prevent galling.

Q: Is this material suitable for water cooling channels?

A: Yes, bronze offers moderate corrosion resistance. For prolonged water exposure, we recommend checking compatibility with your specific coolant chemistry.

Q: Do you provide material certification with the order?

A: Yes, a Mill Test Report (MTR) is available upon request at the time of purchase.

Q: What is the standard lead time for bulk orders?

A: Standard sizes ship within 3-5 business days. Custom machined orders typically take 10-14 business days.

Q: Can you cut these sleeves to custom lengths?

A: Yes, we offer custom machining services. Please contact our sales team with your specific length requirements.
