76.2mm x 44.5mm SAE660 Bronze Tube – High-Strength Bearing Bronze for Engineering Applications

The 76.2mm x 44.5mm SAE660 Bronze Tube is an essential component in various industrial and engineering applications, specifically designed for high-performance tasks. Known for its outstanding strength and durability, this bronze tube is particularly suited for use in bearings and other heavy-duty components where reliability and wear resistance are key.

Material and Grade

Crafted from SAE660 bronze, this tube offers exceptional mechanical properties that make it perfect for high-stress environments. SAE660 bronze, also known as leaded gunmetal, is renowned for its ability to withstand heavy loads and resist wear, making it an ideal choice for bearings, bushings, and other machinery parts. Its self-lubricating properties further enhance its suitability for use in components that require smooth and consistent operation over time.

Key Properties

• Outside Diameter: With an outside diameter of 76.2mm (supplied at 76.9mm), this tube offers the precise sizing needed for a variety of engineering projects.
• Internal Diameter: The tube comes with a supplied internal diameter of 43.6mm, which is machined down to the standard 44.5mm, ensuring a perfect fit for applications that demand high precision.
• Wall Thickness: A 15.8mm wall thickness provides robust structural integrity, allowing the tube to perform reliably under heavy loads without deformation.
• Weight: At 29.72kg per metre, this bronze tube is designed to offer substantial strength while being manageable for machining and installation.

Applications

This SAE660 bronze tube is a preferred material for manufacturing bushings, bearings, and other components that experience high levels of wear and friction. Its self-lubricating properties reduce the need for constant maintenance, making it an ideal choice for industries such as automotive, heavy machinery, and marine applications. The tube's strength and wear resistance allow it to excel in applications where long service life and minimal downtime are required.

Machinability and Weldability

This bronze tube is highly regarded for its excellent machinability, allowing for precise cutting, shaping, and drilling. It is suitable for use in complex engineering processes that require high accuracy. However, its weldability is poor, meaning alternative joining methods, such as brazing, may be required for optimal performance. This limitation should be considered when planning for assembly in specific applications.

Corrosion Resistance and Finish

With fair corrosion resistance, this SAE660 bronze tube can withstand moderate exposure to corrosive environments. This makes it suitable for a range of outdoor or marine applications where other materials may deteriorate quickly. It is supplied with a mill finish, meaning that the surface is unpolished but can be further processed to meet the specific finish requirements of a given project.

Limitations and Considerations

Despite its numerous strengths, the SAE660 bronze tube does have some limitations. Its poor weldability limits its ability to be joined using standard welding techniques, which may require more advanced or alternative methods. Additionally, while it offers fair corrosion resistance, it may require protective coatings or treatments in highly corrosive environments for extended durability.

Conclusion

The 76.2mm x 44.5mm SAE660 Bronze Tube is a top-quality, high-strength material suitable for demanding industrial applications. Its excellent wear resistance, high machinability, and self-lubricating properties make it an invaluable resource for engineers and manufacturers. Whether used in heavy machinery, automotive components, or marine environments, this bronze tube delivers reliable and long-lasting performance, making it a trusted choice for professionals across various industries.
