Anping County Boli Hardware Wiremesh Products Factory (established 1998) specializes in precision-engineered metal components. Our Copper Bushing for Hydraulic Cylinder Pivot Points is designed to withstand extreme loads and repetitive motion, delivering exceptional wear resistance and extended service life. Manufactured from high-grade copper alloys, these bushings reduce friction, prevent galling, and maintain dimensional stability even under harsh operating conditions.
We understand that hydraulic cylinder pivot points are critical to the reliability of heavy machinery. Our bushings are machined to tight tolerances, ensuring a perfect fit with pivot pins and housings. The self-lubricating properties of copper alloys minimize maintenance intervals and downtime. Whether you need standard sizes or custom dimensions, we offer flexible solutions to meet your specific requirements.
Backed by over two decades of manufacturing experience, each bushing undergoes rigorous quality checks. Our factory in Hengshui, Hebei, China, utilizes advanced CNC lathes and inspection equipment to guarantee consistent quality. With an annual export value of US$5 million – US$10 million and shipments to major global markets, we have earned the trust of clients worldwide.
Key Features & Technical Specifications
- Material Excellence: Made from premium copper alloys (e.g., CuSn8, CuZn25Al5) offering high strength, corrosion resistance, and excellent thermal conductivity.
- Wear Resistance: The hard, dense microstructure reduces wear rate by up to 30% compared to standard bronze bushings, extending service life.
- Low Friction Coefficient: Self-lubricating properties minimize the need for external grease, ideal for applications with limited maintenance access.
- Precision Machining: Tolerances as tight as ISO h7/h8 ensure minimal clearance and reduced vibration, protecting pivot pins and housing.
- Customizable Dimensions: We offer inner diameters from 10 mm to 200 mm, outer diameters from 15 mm to 250 mm, and lengths from 20 mm to 300 mm. Non-standard sizes are available upon request.
- Consistent Quality: Each bushing is inspected for hardness, dimensional accuracy, and surface finish (Ra 0.8–1.6 μm).

Benefits for Your Application
- Reduced Downtime: The wear-resistant nature means fewer replacements, keeping your hydraulic cylinders operational longer.
- Lower Maintenance Costs: Self-lubricating properties cut grease consumption and labor for manual lubrication.
- Enhanced Equipment Life: By absorbing shocks and preventing metal-to-metal contact, the bushing protects pivot pins and cylinder bores.
- Versatile Compatibility: Suitable for excavators, loaders, cranes, agricultural machinery, and any hydraulic system with pivot joints.
- Global Logistics: We ship from Tianjin, Qingdao, Shanghai, and Foshan ports, ensuring fast delivery to major markets worldwide.
Frequently Asked Questions (FAQ)
-
Q: What copper alloys do you use for hydraulic cylinder bushings?
A: We primarily use CuSn8 (tin bronze) and CuZn25Al5 (high-strength brass). Both offer excellent wear resistance and load capacity. Other alloys like CuPb10Sn10 can be supplied upon request. -
Q: Can you provide custom sizes?
A: Yes. We can manufacture bushings with any dimensions within our capability range. Please provide your drawings or detailed specifications for a quotation. -
Q: Do these bushings require lubrication?
A: While they have self-lubricating properties, for heavy-duty applications we recommend initial lubrication. The copper alloy microstructure retains oil, reducing relubrication frequency. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 15–20 working days. Custom orders typically take 20–30 working days, depending on complexity and quantity. -
Q: How do you ensure quality consistency?
A: We follow a strict QC process: incoming material inspection, in-process dimensional checks, hardness testing, and final surface finish verification. Each batch is traceable. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 100 pieces for standard sizes. For custom sizes, MOQ may be lower, but please contact us to discuss. -
Q: Can you provide samples for testing?
A: Yes, sample orders are welcome. We charge a nominal fee which is refundable on bulk orders. -
Q: Which markets do you export to?
A: We export to North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and other regions. Our factory has served clients worldwide since 1998.
