As a professional manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our High-Strength Copper Bushing with 360° Oil Grooves – a precision engineered component designed for demanding rotating shaft applications. Our annual export volume of US$5-10 million to global markets such as North America, Europe, and Southeast Asia is a testament to the international trust our products have earned. This bushing combines exceptional strength, advanced lubrication design, and ultra-thin wall thickness to deliver reliable performance in minimal space.
Whether you are designing a new transmission system or upgrading existing machinery, our copper bushing offers a cost-effective solution that reduces friction, extends equipment life, and supports high rotational speeds. Let us help you achieve smoother operation and lower maintenance costs.
Key Features & Technical Specifications
- High-Strength Copper Alloy: Made from specially formulated copper that offers excellent wear resistance, good thermal conductivity, and high load-bearing capacity. Ideal for heavy-duty rotating applications.
- 360° Spiral Oil Grooves: The unique groove pattern ensures uniform distribution of lubricant across the entire bearing surface, minimizing friction and heat generation. This design is particularly effective in intermittent or start-stop operations.
- 0.5mm Ultra-Thin Wall: Allows for compact housing designs while maintaining structural integrity. Perfect for space-constrained assemblies where every millimeter counts.
- Compatible with Rotating Shafts: Designed to accommodate shafts with moderate speeds and loads. Suitable for use in pumps, motors, gearboxes, agricultural equipment, and more.
- Customizable Dimensions: Inner diameter, outer diameter, length, and groove configuration can be tailored to your specific requirements. Contact us for a quote.
- Easy Installation: Can be press-fitted or slip-fitted into housings. No special tooling required.
- Corrosion Resistant: Copper naturally resists many corrosive environments, making it suitable for humid or mild chemical exposure.

Advantages for Your Application
- Reduced Maintenance: The 360° oil grooves ensure continuous lubrication, eliminating the need for frequent re-greasing. This lowers downtime and labor costs.
- Space Saving: At only 0.5mm wall thickness, these bushings allow designers to shrink housing sizes without sacrificing load capacity – ideal for compact machinery.
- Improved Heat Dissipation: Copper’s high thermal conductivity draws heat away from the shaft/ bearing interface, preventing overheating and premature failure.
- Cost-Effective Alternative: Compared to bronze or steel-backed bushings, our copper bushings offer a superior balance of performance and affordability, especially for series production.
- Global Compatibility: Shipped from our ports in Tianjin, Qingdao, Shanghai, and Foshan, we serve customers in over 20 countries with consistent quality and lead times.

Frequently Asked Questions
-
Q: What material is this copper bushing made of?
A: It is made from a high-strength copper alloy specifically formulated for bearing applications. The exact composition (e.g., copper content, trace elements) is available upon request to ensure compliance with your project requirements. -
Q: Can you customize the inner diameter and length?
A: Yes, absolutely. We offer full customization of all dimensions, including ID, OD, length, and wall thickness (within reasonable limits). Just provide your drawing or specifications, and we will produce a sample for approval. -
Q: How does the 360° oil groove improve performance?
A: The spiral groove ensures that lubricant (oil or grease) is distributed evenly around the entire circumference of the bushing. This prevents dry spots, reduces friction, and extends the service life of both the bushing and the shaft. -
Q: What is the maximum allowable load for a 0.5mm wall thickness bushing?
A: Load capacity depends on several factors including shaft diameter, speed, lubrication, and operating temperature. As a general guideline, our bushings can handle moderate to high loads for their size. We recommend consulting our engineering team for a precise calculation based on your specific parameters. -
Q: How does this bushing compare to bronze or steel bushings?
A: Copper bushings offer better thermal conductivity and corrosion resistance than steel, and are often more cost-effective than bronze. They are an excellent choice for applications where weight savings and heat dissipation are important. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, we can ship within 2-3 weeks. Custom orders typically require 3-5 weeks depending on complexity and quantity. We also offer expedited services for urgent needs. -
Q: Do you provide samples before mass production?
A: Yes, we encourage sample testing. We can produce a sample based on your drawing or our standard dimensions. Sample cost is negotiable and will be deducted from the final order if you proceed with mass production. -
Q: How do I install these bushings – press fit or slip fit?
A: Both methods are possible. For press fit, ensure the housing bore is slightly undersized (typically 0.02-0.05mm interference). For slip fit, use a clearance fit and secure with retaining rings or adhesive. Our technical support team can provide guidance based on your assembly.
