High-Precision Oil-Impregnated Sintered Bronze Bushings for Demanding Applications
As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality oil-impregnated sintered bronze bushings. Our 0.3mm wall thickness bushings are engineered to deliver exceptional dimensional accuracy and self-lubricating performance, making them ideal for applications where space is limited and maintenance is difficult. With annual export value exceeding US$5 million and a global distribution network covering North America, Europe, Asia, and beyond, we provide reliable solutions for OEMs, industrial machinery manufacturers, and automotive component suppliers. Each bushing undergoes strict quality control to ensure compliance with ISO 9001 standards, offering you consistent performance and long service life.
Key Features and Technical Specifications
- Self-Lubricating Design: The porous bronze structure is vacuum-impregnated with high-grade lubricating oil, providing continuous lubrication during operation without external oil supply. This reduces friction, wear, and maintenance frequency.
- Precision 0.3mm Wall Thickness: Ultra-thin wall design allows for compact assemblies and tight tolerance fits. The wall thickness is held to ±0.02mm, ensuring consistent performance in high-precision applications.
- High Yield Strength (60 MPa): The sintered bronze material offers excellent mechanical strength and load-carrying capacity, suitable for moderate to heavy loads in rotating or oscillating motions.
- Excellent Wear Resistance: The combination of bronze matrix and oil impregnation provides low coefficient of friction (typically 0.04–0.10) and minimal wear, extending component life.
- Corrosion and Chemical Resistance: Bronze is inherently resistant to corrosion, moisture, and many chemicals, making these bushings suitable for harsh environments such as food processing, marine, and outdoor equipment.
- ISO 9001 Quality Management: Our manufacturing facilities are certified to ISO 9001, ensuring consistent quality from raw material selection to final inspection. Each batch is traceable.
- Customizable Dimensions: While standard sizes are available, we offer custom inner diameters (ID), outer diameters (OD), and lengths to meet your specific design requirements. Customized oil types and impregnation levels are also available upon request.
- Broad Temperature Range: These bushings operate effectively from -40°C to +150°C, with temporary peaks up to +200°C depending on oil type.
Typical Technical Parameters
| Parameter | Value |
|---|---|
| Wall Thickness | 0.3 mm (±0.02 mm) |
| Yield Strength | 60 MPa (minimum) |
| Density | 6.4–7.0 g/cm³ |
| Oil Content (by volume) | 15–25% |
| Hardness (HB) | 40–70 |
| Max Operating Temperature | 150°C (continuous) |
| Coefficient of Friction | 0.04–0.10 (self-lubricated) |
Applications and Benefits
- Automotive: Gearbox bushings, throttle linkages, suspension components – where low friction and long maintenance intervals are required.
- Industrial Machinery: Conveyor rollers, printing presses, textile machinery, packaging equipment – the self-lubricating feature eliminates the need for grease fittings.
- Household Appliances: Washing machines, fans, vacuum cleaners – quiet operation and reduced stick-slip.
- Agricultural Equipment: Pivot points, linkages, and small bearings subject to dust and moisture – bronze resists corrosion and retains lubrication.
- Medical Devices: Low-friction, silent operation for devices like hospital beds, imaging equipment, and diagnostic tools.
- Office Equipment: Printer rollers, copier mechanisms – consistent performance over millions of cycles.
By choosing our oil-impregnated sintered bronze bushings, you benefit from reduced maintenance costs, extended equipment life, and improved energy efficiency due to lower friction. The 0.3mm wall thickness allows design engineers to downsize assemblies without sacrificing strength or reliability.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of these bushings?
A: The lifespan depends on load, speed, and operating conditions. Under normal industrial loads (e.g., 5–10 MPa) and moderate speeds, they can last 3,000–8,000 hours. The self-lubricating feature ensures consistent performance even after extended use. -
Q: Can these bushings be used in high-temperature environments?
A: Yes, they operate continuously up to 150°C. For higher temperatures, we can adjust the oil type or use a different impregnation method. Please consult our engineers for specific requirements. -
Q: Do you offer custom sizes?
A: Absolutely. We can produce bushings with custom inner diameters (from 2 mm to 200 mm), outer diameters, and lengths. Minimum order quantity may apply for non-standard sizes. -
Q: How do I install these bushings?
A: The bushings are designed for press-fit into housings with recommended interference fits (e.g., H7/p6). We provide installation guidelines to avoid deformation of the thin wall. For 0.3mm wall thickness, careful pressing is required to maintain dimensional accuracy. -
Q: Are these bushings RoHS compliant?
A: Yes, our bronze material is RoHS compliant (lead-free bronze upon request). We can also provide REACH and other compliance documentation as needed. -
Q: What is the oil type used for impregnation?
A: We typically use high-viscosity mineral oil (ISO VG 68 or 100) for general applications. For food-grade or medical applications, we can use FDA-approved lubricants. Please specify your requirements. -
Q: Can I get a sample before mass production?
A: Yes, we offer sample orders. For standard sizes, samples are available in 1–2 weeks. Custom samples may take 3–4 weeks. Sample cost is negotiable, and we will deduct it from your first bulk order. -
Q: What is your packaging and shipping method?
A: We pack bushings in moisture-proof bags and then in sturdy cartons or wooden crates, depending on quantity. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports via sea, air, or express. We can also use your preferred forwarder.
