PBC2 Phosphor Bronze Bearing
PBC2 Phosphor Bronze Bearing
PBC2 Phosphor Bronze Bearing – JIS CAC502 Standard Economical Phosphor Bronze Bushing – Bulk Custom Bearings
Unlock the perfect balance of performance and cost-efficiency with our PBC2 Phosphor Bronze Bearings. Manufactured strictly to the JIS CAC502 standard, these bushings are designed for medium-load applications where corrosion resistance and low friction are paramount—such as chemical pumps and industrial fans.
Unlike high-cost alternatives, our PBC2 series utilizes an optimized casting process that reduces production costs by up to 20%, making it the ideal choice for high-volume OEM supply chains. Experience reliable operation with excellent ductility and machinability.
Material Specifications & Performance Data
Designed for the Asian and Global markets requiring JIS adherence, PBC2 offers distinct advantages over standard bronzes. While avoiding the excessive hardness of high-tin alloys, PBC2 focuses on ductility and ease of machining, allowing for rapid customization and tight tolerances.
Our sand casting process prioritizes high consistency, ensuring that every batch meets the rigorous demands of OEM assembly lines.
Selection Note:
PBC2 offers significant economic casting advantages based on the JIS CAC502 standard.
Need Higher Load Capacity? If your application requires superior strength for European heavy industry, please view our PB2 Phosphor Bronze Bearing (BS1400 certified).
Technical Data Sheet (JIS CAC502 / PBC2):
| Property | Value / Range | Key Benefit for Your Application |
| Composition (wt%) | Cu 87-91%, Sn 9-12%, P 0.05-0.5% | Optimal balance of strength and anti-seizing properties. |
| Tensile Strength | ≥ 195 MPa | Sufficient durability for general machinery without brittleness. |
| Hardness | HB 60 (approx.) | Excellent Ductility: Conforms well to shafts, reducing wear on mating parts. |
| Friction Coefficient | < 0.2 (Lubricated) | Energy-efficient operation in continuous rotation. |
| PV Value | > 40,000 | Reliable performance in medium-speed environments. |
| Dimensions | ID 8-120mm, Length 10-200mm | Fully customizable sizes for diverse equipment. |
Production Note: Unlike continuous casting focused on extreme density, our PBC2 sand casting technique provides superior cost-performance for standard industrial parts, verified for structural integrity.
Application Scenarios: Reliability in Motion
Our PBC2 bearings are engineered for sectors that demand consistent uptime and chemical stability. We move away from heavy impact zones to focus on precision and corrosion resistance.
1. Chemical Pump Systems
In acidic and alkaline environments, standard steel fails. PBC2’s phosphor content creates a protective film, extending bearing life.
-
Performance metric: Validated maintenance intervals exceeding 800 hours in continuous pumping operations.
2. Industrial Fan Components
For ventilation and cooling systems, noise reduction is critical. The softer, damping nature of JIS CAC502 bronze ensures silent running compared to harder alloys.
-
Benefit: Optimized sliding properties reduce vibration and lower replacement costs.
Engineering Insight:
For medium-speed fans, the PBC2’s PV value of >40,000 is sufficient and cost-effective. However, if your system involves significant shock or impact loads, please refer to our PB1 vs PB2 Phosphor Bronze Bearing Comparison guide to select the best match for extreme durability.
3. General Machinery & Gearboxes
Ideal for medium-speed gearboxes where budget and performance must meet.
