C86500 Alloy

Graphite self-lubricating bronze bushings are engineered bearings crafted for robust and low-maintenance performance across strenuous industrial settings. These bushings merge the inherent mechanical strength of bronze with graphite’s self-lubricating attributes, making them perfect for high-load and low-speed applications where traditional lubrication might be impractical.

Advantages of Graphite Self-Lubricating Bronze Bushings

Self-Lubrication: Embedded graphite plugs in the bushing release lubricant particles during operation, cutting down friction and obviating the need for external lubrication systems. This results in reduced maintenance and ensures steady lubrication, even in inaccessible areas.

Reduced Friction and Wear: Graphite serves as a solid lubricant, creating a lubricative film that diminishes direct metal-to-metal contact, significantly lowering wear on both the bushing and interacting surfaces, thus prolonging their operational life.

High Load Capacity: Bronze bushings are renowned for their substantial load-bearing capabilities. Augmented with graphite’s self-lubricating properties, these bushings endure high pressures and loads with minimal wear or damage, suitable for intense applications.

Corrosion Resistance: These bushings are impervious to corrosion, ideal for use in moist or mildly corrosive settings. They withstand exposure to moisture and certain chemicals without degrading in performance or durability.

Wide Temperature Range: Graphite self-lubricating bushings exhibit excellent thermal conductivity and function effectively across a broad temperature spectrum. They retain their lubricating efficacy and mechanical integrity at both high and low temperatures.

Maintenance and Cost Savings: The self-lubricating nature of these bushings minimizes the necessity for frequent maintenance and lubrication, recognized to savings on labor, downtime, and lubrication costs. Their prolonged service life further lowers total expenses by reducing replacement frequency.

C86500 Alloy as an Option The C86500 alloy, also known as manganese bronze, is a robust copper alloy utilized in bronze bushing manufacture. Primarily composed of copper, manganese, aluminum, and iron, it offers superior mechanical properties and notable corrosion resistance. This alloy is adept at managing very high loads and speeds, making it apt for bearing applications.

Key Properties of C86500 Alloy:

• High Tensile Strength: Exceeding 110,000 KSI, suitable for high-stress scenarios.
• Corrosion Resistance: Performs well in saline and other mildly corrosive environments, ideal for marine and industrial uses.
• Thermal Conductivity: Exhibits good thermal management, enabling stable performance under varying temperatures.

Applications Graphite self-lubricating bronze bushings find application across numerous industries, including:

• Oil and Gas: For equipment demanding reliable operation under intense loads and extreme conditions.
• Industrial Mixers and Machinery: Where consistent lubrication and reduced maintenance are paramount.
• Seawater Applications: Leveraging their corrosion resistance for operation in moist environments.
• Agricultural Equipment: Valued for their durability and maintenance ease.

In conclusion, graphite self-lubricating bronze bushings, especially those crafted from C86500 alloy, provide a durable solution for challenging industrial applications. Their blend of self-lubrication, high load capacity, and corrosion resistance renders them an essential component for enhancing machinery efficiency and reliability.
