Superior heat dissipation
Our previous bronze bushings were overheating under high friction. These copper liners run much cooler. Great solution for high-speed rotating equipment.

Good quality, precise fit
The machining tolerance was spot on for our custom application. Installation was smooth. Only giving 4 stars because the delivery took a day longer than expected, but the product itself is top-notch.

Cost-effective longevity
While the unit price is slightly higher than generic options, the extended service life makes these much more cost-effective in the long run. Less downtime for replacements.

Reliable supplier for industrial parts
This is our third order. Consistency in quality is key for our production line, and this manufacturer delivers every time. The HRB-78 alloy holds up well against abrasive materials.

Solid performance
Works exactly as described. The surface finish is very smooth which reduced initial break-in time. Would recommend for anyone needing robust bearing solutions.

Excellent durability for heavy loads
We replaced our standard bushings with these HRB-78 copper liners in our conveyor system. The wear resistance is noticeably better, and we haven't seen any deformation after three months of 24/7 operation.
Q: What is the maximum operating temperature for the HRB-78 alloy?
A: The HRB-78 copper liner maintains its structural integrity and wear resistance up to approximately 250°C (482°F). For higher temperatures, please contact us for alternative alloy recommendations.
Q: What is the typical lead time for a bulk order of 500 units?
A: For an order of 500 units, the standard lead time is approximately 10-12 business days from the confirmation of final specifications. Expedited processing is available upon request.
Q: Do you provide material certification with the shipment?
A: Absolutely. Every batch comes with a Mill Test Certificate (MTC) detailing the chemical composition and mechanical properties to ensure compliance with stated specifications.
Q: Can you manufacture these liners to non-standard dimensions?
A: Yes, we offer full OEM customization. Please provide your technical drawings or specific dimension requirements, and our engineering team will provide a quote.
Q: Is lubrication required during installation?
A: We recommend applying a thin layer of appropriate industrial grease during installation to prevent galling and ensure smooth initial operation until the running-in period is complete.
