Oil-Impregnated (Self-Lubricating)
Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience (since 1998) in producing high-quality powder metal components. Our Oil-Impregnated Powder Metal Bearing Bushing with 18% porosity and a low friction coefficient of 0.12 is engineered to deliver reliable, self-lubricating performance in demanding applications. As a company with an annual export value of US$5–10 million and shipments to major ports like Tianjin, Qingdao, and Shanghai, we serve global markets including North America, Europe, Southeast Asia, and the Middle East. This bushing is a cost-effective solution for reducing maintenance and extending equipment life.
Key Features & Technical Specifications
- Self-Lubricating Design: The 18% interconnected porosity is impregnated with high-quality lubricating oil, providing continuous lubrication without external oiling systems. This reduces downtime and operational costs.
- Low Friction Coefficient (0.12): Achieves smooth operation under moderate loads and speeds, minimizing wear on mating shafts and extending bearing life.
- Powder Metal Construction: Manufactured through precision sintering of metal powders (bronze or iron-based), ensuring uniform density, dimensional accuracy, and excellent load-bearing capacity.
- Quiet Operation: The oil film dampens vibration and noise, ideal for applications requiring low noise levels.
- Customizable Dimensions: Available in a wide range of inner diameters, outer diameters, and lengths. Custom sizes can be produced quickly to meet your specific requirements.
- Wide Operating Temperature Range: Suitable for continuous use from -20°C to +120°C, with peak short-term tolerance up to 150°C.
| Parameter | Value |
|---|---|
| Porosity | 18% ± 2% |
| Friction Coefficient | 0.08 – 0.12 (dry start) / 0.12 (steady state) |
| Hardness (HB) | 30 – 60 (depending on material) |
| Max Operating Temperature | 120°C continuous / 150°C intermittent |
| Max PV Value (permissible) | 2.5 MPa·m/s (for bronze base) |
| Standard Sizes (ID × OD × Length) | From 3mm × 6mm × 6mm up to 100mm × 120mm × 100mm (custom available) |
Benefits for Your Application
- Reduced Maintenance: Self-lubrication eliminates the need for grease fittings, oil lines, or frequent relubrication, saving labor and lubricant costs.
- Long Service Life: The oil-impregnated structure provides a steady lubricant supply over thousands of operating hours, especially in low-speed, oscillating, or intermittent duty cycles.
- Cost-Effective: Powder metal manufacturing allows for high-volume production with tight tolerances, offering a lower per-unit cost compared to machined bronze bearings.
- Versatile Compatibility: Works well with steel, stainless steel, and hardened shafts. Ideal for use in agricultural machinery, power tools, office equipment, automotive components, and conveyor systems.
- Environmental Friendliness: No dripping oil or mist, making it suitable for clean environments like food processing or textile machinery.

Frequently Asked Questions (FAQ)
- How does oil-impregnated bearing work? The bearing is sintered with controlled porosity (18% here), then vacuum-impregnated with oil. During operation, heat causes the oil to expand and form a thin film on the surface, lubricating the shaft. When stationary, oil reabsorbs into the pores.
- What is the maximum load capacity? Load capacity depends on material and size. For our bronze-based bushing, the maximum PV value is 2.5 MPa·m/s. For specific loads, please consult our technical team.
- Can you provide custom sizes? Yes, we can produce bushings with custom inner diameters, outer diameters, lengths, and even flanged designs. Minimum order quantity may apply for custom parts.
- Is this bearing suitable for high-speed applications? This bearing is optimized for low to moderate speeds (up to 2 m/s sliding velocity). For high-speed or high-load applications, we recommend other self-lubricating designs.
- What is the expected service life? Service life varies based on load, speed, temperature, and contamination. Under typical conditions (moderate load, clean environment), it can last 3,000–10,000 hours. Regular oil replenishment (if possible) can extend life.
- Does the bearing need initial lubrication before use? No, it is pre-lubricated with oil during manufacturing. However, in some applications, a thin layer of grease on the shaft can help during initial run-in.
- Are these bushings RoHS compliant? Our standard materials are RoHS compliant. Please confirm your specific requirements when ordering.
- What is the difference between 18% porosity and other porosity levels? Higher porosity (e.g., 25-30%) holds more oil but reduces mechanical strength. 18% offers a good balance between oil retention and load capacity for many industrial applications.
