101.6mm x 88.9mm (4" OD x 3 1/2" ID) SAE660 Bronze Tube - High Strength, Wear Resistant, Leaded Bronze for Bearings, Bushings & Industrial Applications - Linear Metre

101.6mm x 88.9mm SAE660 Bronze Tube: Specifications and Benefits

The 101.6mm x 88.9mm (4" OD x 3 1/2" ID) SAE660 Bronze Tube is a highly versatile and durable material, commonly used in industrial and engineering applications. Manufactured from SAE660 bronze, this tube is engineered for strength, reliability, and longevity, making it an ideal choice for applications requiring resistance to wear and moderate corrosion. Here's a closer look at its key features and benefits:

Material Composition and Grade

This bronze tube is composed of SAE660 bronze, a high-leaded tin bronze alloy. Known for its excellent machinability, SAE660 offers superior performance in applications where lubrication is challenging. Its composition allows it to retain strength under high temperatures and in heavy-duty settings, making it a popular choice in the manufacture of bearings, bushings, and other moving parts where friction is a concern.

Dimensions and Structure

• Outside Diameter (OD): 101.6mm (4 inches)
• Internal Diameter (ID): 88.9mm (3 1/2 inches)
• Wall Thickness: 6.3mm
• Weight per Metre: 21.32 kg

The tube's outside diameter is 101.6mm, providing a strong, solid structure. Its wall thickness of 6.3mm ensures durability, helping to withstand wear and pressure over extended periods of use. With a weight of 21.32 kg per metre, this bronze tube offers a sturdy yet manageable material solution for various applications.

Applications and Performance

SAE660 bronze is widely utilised for its low friction properties and high wear resistance. It is ideal for bearings and bushings in heavy machinery, as it operates well under load with moderate speed and pressure. This bronze tube's fair corrosion resistance makes it suitable for marine environments or machinery exposed to moisture, though additional coatings may be required for prolonged use in harsh environments.

Welding and Machining

While SAE660 bronze is poor in weldability, it excels in machinability, allowing precise shaping and fitting to exact specifications. It is often recommended to avoid welding and instead focus on mechanical assembly or fastening techniques to maintain the integrity of the material.

Surface Finish

This bronze tube is supplied in a mill finish, which refers to the raw, unpolished surface straight from the manufacturing process. The mill finish provides an industrial look, and the tube may require further polishing or finishing based on the specific aesthetic or functional requirements of its application.

Summary of Benefits

• High Lead Content: Offers excellent machinability and reduces friction in bearing applications.
• Durability: Thick walls (6.3mm) ensure long-lasting use, even under stress.
• Corrosion Resistance: Moderate resistance, making it suitable for damp environments.
• Versatile Applications: Ideal for bearings, bushings, and heavy machinery components.

The 101.6mm x 88.9mm SAE660 bronze tube is a reliable, high-performance material ideal for industries requiring durable, low-friction components. Its balance of strength, machinability, and moderate corrosion resistance makes it an essential material for a wide range of engineering and industrial applications.
