Excellent durability for high-cycle molds
We replaced our standard brass bushings with these graphite bronze sleeves in our injection molding line. The self-lubricating feature has significantly reduced downtime for maintenance. Highly recommended for heavy-duty applications.

Solid industrial component
Very robust construction. We use these in our die-casting units. They handle the thermal expansion well. Would give 5 stars if the packaging was slightly more protective for international shipping.

Good precision, slight lead time
The dimensional accuracy is spot on for our precision guides. The only reason for 4 stars is the shipping took a bit longer than expected, but the product quality makes up for it.

Solved our overheating issue
Our previous bushings would seize under high friction heat. These oil-impregnated graphite bushings run cool and smooth even after continuous operation. A game changer for our machinery.

Cost-effective longevity
Initially thought the price was higher than standard bushings, but the lifespan is triple that of our old parts. The reduction in lubrication costs also adds up. Great value overall.
Q: Is this material suitable for underwater or wet environments?
A: Yes, the bronze-graphite composite offers excellent corrosion resistance and performs well in wet or humid environments, though extreme saltwater exposure should be discussed with our engineers.
Q: What is the typical lead time for a batch of 500 units?
A: Standard sizes are often in stock and ship within 3-5 days. For a batch of 500 custom units, the typical production lead time is approximately 15-20 business days.
Q: Do you offer custom machining for non-standard inner diameters?
A: Absolutely. We can manufacture custom sizes based on your technical drawings. Please contact our sales team with your specific ID, OD, and length requirements for a quote.
Q: What is the maximum shaft speed recommended for this material?
A: For optimal performance and longevity, we recommend a maximum sliding speed of 2.5 m/s under standard load conditions. Higher speeds may require specific cooling considerations.
Q: Can these bushings operate without external grease or oil application?
A: Yes, these are self-lubricating bushings impregnated with oil and embedded with solid graphite plugs, designed to operate efficiently without external lubrication.
