Great durability under heat

These bushings handle the thermal expansion in our die-casting operations very well. The only reason for 4 stars instead of 5 is that the lead time was slightly longer than expected, but the quality makes up for it.

Excellent technical support

We needed a custom oil groove pattern for a specific application. The manufacturer worked closely with our engineering team to deliver a bespoke solution that performed flawlessly during testing.

Eliminated sticking issues

Previously, we had frequent sticking issues with guided ejection plates. After installing these oil-impregnated composite sleeves, the movement is smooth and consistent even after millions of cycles.

Cost-effective long term

While the unit price is higher than standard bronze bushings, the extended service life and elimination of external lubrication systems make these much more cost-effective over the year.

Solid performance for heavy loads

Using these in a heavy-duty stamping press. They hold up well under significant lateral pressure. The graphite content provides just enough lubrication without attracting too much debris.

Perfect fit for our injection molds

We replaced our standard brass bushings with these graphite copper sleeves in our high-cycle injection molding machines. The self-lubricating feature has significantly reduced our maintenance downtime. Precision is exactly as specified.

5 FAQ

Q: Can these bushings be used in food-grade packaging machinery?

A: Yes, provided the specific alloy meets FDA requirements for incidental contact. Please contact our sales team to request our food-grade certified variant which uses NSF-approved lubricants.

Q: What is the recommended shaft hardness when pairing with this sleeve?

A: We recommend a shaft hardness of at least 50 HRC to prevent galling and ensure optimal wear life for the graphite-copper composite material.

Q: How does the oil impregnation work over time? Does it run out?

A: The porous graphite structure acts as a reservoir. As friction generates heat, microscopic amounts of oil are released to the surface. Once the machine cools, the oil is re-absorbed. This cycle continues for the life of the part under normal operating conditions.

Q: Do you offer custom sizes if our mold design requires non-standard dimensions?

A: Absolutely. We specialize in custom manufacturing. Please provide your CAD drawings or detailed dimension sheets, and our engineering team will provide a quote within 48 hours.

Q: Are these suitable for underwater or submerged applications?

A: While they are oil-impregnated, continuous submersion in water can eventually displace the internal lubricant. For submerged applications, we recommend our specialized marine-grade composite sleeves with sealed ends.
