Where to Use Graphalloy Bearings and Bushings: A Comprehensive Guide to VIIPLUS Solutions
In industries where extreme temperatures, heavy loads, and corrosive environments are the norm, Graphalloy bearings and bushings have emerged as a game-changer. Combining the strength of metal alloys with the self-lubricating properties of graphite, these components eliminate the need for grease, reduce downtime, and extend equipment lifespan. VIIPLUS, a leading Chinese manufacturer, engineers Graphalloy solutions tailored to the most demanding applications. This guide dives deep into their material science, industry-specific use cases, and why they outperform traditional bearings.
Graphalloy bearings feature a bronze or steel matrix embedded with solid graphite plugs, creating a self-lubricating surface that reduces friction by 60–80%. Key advantages include:
Zero Maintenance: No external lubrication required.
Extreme Temperature Resistance: Operates from -200°C to +350°C.
Corrosion Resistance: Withstands acids, alkalis, and moisture.
High Load Capacity: Supports up to 250 MPa (depending on material).
VIIPLUS offers a range of Graphalloy-compatible alloys optimized for specific challenges:
| Material | Composition | Key Properties | Max Load | Temperature Range |
|---|---|---|---|---|
| C95400 Aluminum Bronze | Cu + Al + Fe + Ni | High strength, corrosion resistance | 250 MPa | -30°C to +300°C |
| C86300 Manganese Bronze | Cu + Zn + Mn + Al | Shock absorption, wear resistance | 200 MPa | -50°C to +250°C |
| C93200 Tin Bronze | Cu + Sn + Zn + Pb | Low friction, FDA compliance | 150 MPa | -20°C to +200°C |
