High-Performance Solutions for Heavy Industries: VIIPLUS C86300 Manganese Bronze Bushings & VSB-50 Bearings
In industries where machinery faces extreme loads, corrosive environments, and relentless operational stress, the choice of bushings becomes pivotal. VIIPLUS addresses these challenges with C86300 (SAE 430B) Manganese Bronze Bushings and VSB-50 Self-Lubricating Bearings, engineered to deliver durability, reduced maintenance, and precision. This article explores their material properties, application-specific advantages, and how they outperform conventional alternatives—supported by data-driven insights for informed decision-making.
C86300 is a high-strength bronze alloy renowned for its exceptional load-bearing capacity and wear resistance. Key attributes include:
Composition: Copper (60–70%), Zinc (22–28%), Manganese (2.5–4%), Iron (2–4%), Aluminum (5–7.5%).
Mechanical Properties:
Tensile Strength: 750–900 MPa
Yield Strength: 400–550 MPa
Hardness: 180–220 HB
Standards: Compliant with DIN 1850 and ISO 4379 for dimensional precision.
Lubrication: Embedded lubricant plugs enable maintenance-free operation under low-speed, high-load conditions.
Selecting the right alloy depends on operational demands. Below is a comparative analysis:
| Property | C86300 (Manganese Bronze) | C95400 (Aluminum Bronze) | C93200 (Tin Bronze) |
|---|---|---|---|
| Tensile Strength (MPa) | 750–900 | 620–800 | 200–250 |
| Max Load Capacity | Extreme | High | Moderate |
| Corrosion Resistance | Moderate | Excellent | Excellent |
| Temp Limit | 260°C | 400°C | 200°C |
| Best For | Heavy machinery, marine apps | High-temp, corrosive environs | Low-load, high-speed |
Key Takeaway: C86300 excels in high-impact, low-speed environments like steel mills and earth-moving equipment, while C95400 is better suited for extreme temperatures, and C93200 for corrosion-prone settings.
Use Cases: Rolling mill guides, conveyor rollers, valve stems.
Why C86300? Withstands heavy loads (up to 900 MPa) and abrasive particles in steel processing.
Use Cases: Propeller shaft bushings, hydraulic cylinder sleeves.
Why C86300? Resists saltwater corrosion and galvanic degradation.
Use Cases: Excavator pivot joints, bulldozer track rollers.
Why C86300? Handles shock loads and prolonged vibration without wear.
Use Cases: Cylinder sleeves, pump components.
Why C86300? Maintains dimensional stability under high-pressure cycles.
VSB-50 bearings enhance C86300’s capabilities with solid lubricant pockets and a PTFE film, eliminating the need for external grease.
| Feature | VSB-50 Bearings | Standard C86300 Bushings |
|---|---|---|
| Lubrication | Self-lubricating, maintenance-free | Requires periodic grease |
| Load Capacity | 150–200 MPa | 750–900 MPa |
| Speed | Low to medium | Very low |
| Best For | Intermittent motion, harsh environs | Continuous heavy-load apps |
