Bunting Bearings Cast Bronze Bar 3/4″ Bore x 1.25″ OD x 13″ Length

Description

Product Overview

The Bunting Bearings Cast Bronze Bar is engineered for precision and durability in demanding industrial settings. Constructed from high‑lead tin bronze (SAE 660), this 13‑inch long tube provides a 3/4‑inch bore and a 1.25‑inch outer diameter, delivering a robust core that resists deformation and wear. Its non‑magnetic composition makes it ideal for applications where magnetic interference must be avoided, such as in sensitive instrumentation or electromagnetic environments. The bar’s uniform wall thickness and smooth surface finish enable easy machining, drilling, and threading, reducing setup time and tool wear. With a weight of approximately 3.9 pounds, it balances strength and manageability, allowing technicians to handle and install the component with minimal effort. The product is listed under the Bronze Tubes category and holds a strong ranking among industrial raw materials, reflecting its reliability and popularity among manufacturers seeking high‑quality bronze tubing.

Usage

Designed for a wide range of industrial applications, this bronze bar excels in machine blanks, custom tooling, and prototype development. Its non‑magnetic property is especially valuable in aerospace, automotive, and electronics manufacturing where magnetic fields can affect performance. The bar can be used as a shaft, spacer, or structural component in CNC machines, hydraulic systems, and precision assemblies. Its high‑lead tin bronze alloy offers excellent corrosion resistance, making it suitable for environments exposed to moisture, chemicals, or temperature fluctuations. Engineers often select this bar for creating custom fixtures, jigs, and molds because it can be easily machined to exact dimensions without compromising structural integrity. Additionally, the bar’s length and bore size provide a convenient starting point for fabricating longer assemblies or integrating into modular systems, allowing for scalable production and rapid iteration.

FAQ

What machining processes are recommended for this bronze bar?

The bar can be safely turned, drilled, milled, and tapped using standard carbide or high‑speed steel tools. Because the material is non‑magnetic and has good machinability, you can achieve tight tolerances without excessive tool wear.

Is the bar suitable for high‑temperature applications?

Yes. The high‑lead tin bronze alloy maintains its mechanical properties up to approximately 600°F (315°C), making it appropriate for many heat‑exposed environments, though prolonged exposure above this range should be evaluated for specific use cases.

Can this product be ordered in custom lengths or diameters?

Bunting Bearings offers custom machining services for bulk orders. Contact our sales team with your required dimensions, and we can provide a quote for tailored lengths, bore sizes, or additional finishing options.

What is the difference between this bronze bar and standard steel tubing?

Bronze provides superior corrosion resistance, non‑magnetic properties, and better wear characteristics in certain applications. While steel offers higher tensile strength, bronze is often preferred where conductivity, lubrication, or magnetic neutrality is critical.

How do I verify the material composition of the bar?

Each shipment includes a material certification report that details the alloy composition, heat‑treatment process, and compliance with ASTM B505 standards, ensuring traceability and confidence in material performance.
