Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export values ranging from US$5 million to US$10 million. Our high-precision copper bushing, designed to meet DIN 1498 standards, delivers exceptional roundness of 0.005mm and concentricity of 0.02mm, ensuring reliable performance in demanding applications. With decades of machining expertise and a global market reach including North America, Europe, and Asia, we are committed to providing components that optimize equipment longevity and operational efficiency.
This bushing is precision-engineered for industries requiring minimal tolerance variations, such as automotive transmissions, heavy machinery, and precision instruments. Its superior dimensional accuracy reduces vibration, noise, and wear, extending the service life of assembled parts. Below, we detail the technical specifications and benefits that make this product a preferred choice for OEMs and maintenance professionals worldwide.
Key Technical Specifications
| Parameter | Value | Remarks |
|---|---|---|
| Material | Copper (Cu) | High-purity copper for excellent thermal and electrical conductivity |
| Roundness | 0.005 mm | Ensures uniform load distribution and minimal friction |
| Concentricity | 0.02 mm | Critical for precise alignment in rotating assemblies |
| Standard | DIN 1498 | Complies with German industrial standards for bushings |
| Surface Finish | Ra ≤ 0.8 μm | Smooth surface reduces wear and improves lubrication retention |
| Hardness | 80–100 HB | Balanced hardness for durability and machinability |
Product Features and Benefits
- Exceptional Dimensional Precision: With roundness controlled to 0.005mm and concentricity to 0.02mm, our bushing guarantees reliable fitment in high-speed or high-load applications, reducing the risk of premature failure.
- Compliance with DIN 1498: Manufactured to strict German standards, ensuring interchangeability and consistent quality across batches. This makes it suitable for both replacement and original equipment.
- Superior Material Properties: Copper offers excellent corrosion resistance, thermal conductivity, and self-lubricating characteristics, which help dissipate heat and reduce maintenance frequency in continuous operation environments.
- Versatile Application Range: Ideal for use in pumps, compressors, electric motors, gearboxes, and agricultural machinery. The bushing performs well under both static and dynamic loads.
- Customizable Dimensions: We offer custom sizing and finishing options (e.g., oil grooves, flanges) to meet specific design requirements. Contact our engineering team for tailored solutions.
- Cost-Effective Performance: Our precision manufacturing process minimizes material waste and ensures consistent quality, delivering long-term value through reduced downtime and replacement costs.
Why Choose Our Bushing?
Compared to standard bushings, our product offers tighter tolerances that directly translate to smoother operation and longer equipment life. For example, in a high-speed spindle application, the 0.005mm roundness reduces vibration amplitude by up to 30% compared to conventional bushings (based on internal testing). Additionally, the concentricity of 0.02mm ensures that rotating shafts remain centered, preventing uneven wear on bearings and seals.
Our manufacturing facility in Hengshui, Hebei, China, is equipped with advanced CNC lathes and grinding machines, operated by skilled technicians with over 20 years of experience. Every batch undergoes rigorous inspection using CMM (Coordinate Measuring Machine) and roundness testers to ensure compliance with the stated tolerances.
Trust Our Proven Track Record
As a manufacturer with a strong export presence (annual export value US$5–10 million), we have successfully supplied precision components to markets including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and Western Europe. Our long-standing business relationships with clients in the automotive and industrial sectors testify to our reliability and product quality.
We are confident that our high-precision copper bushing will meet or exceed your expectations. To request a quotation, discuss custom requirements, or place an order, please contact our sales team. We typically respond within 24 hours and can arrange shipment from Tianjin, Qingdao, Shanghai, or Foshan ports.
