Brass Bronze Round Tube — Precision OD/ID Stock for Bushings, Spacers & Structural Applications

When a project calls for a reliable hollow cylinder with a specific bore and wall thickness, finding the right brass bronze round tube in the exact OD-to-ID ratio can be frustrating. Machinists, maintenance technicians, and DIY fabricators who need ready-to-use bronze tube stock — without ordering custom extrusions — will find this range covers the most common metric combinations in a single, convenient 100mm section.

Each piece is a solid-wall bronze round tube available in outer diameters from 25mm (≈0.98") to 95mm (≈3.74") and inner diameters from 15mm (≈0.59") to 75mm (≈2.95"), with a fixed length of 100mm (≈3.94"). Wall thickness varies by combination — from approximately 5mm up to 22.5mm — giving you a wide range of structural weights. Sold individually (1 pc per order) with 54 OD × ID combinations available as variants.

Typical use cases include replacement sleeve bushings for agricultural and industrial equipment, bronze spacer tubes for shaft assemblies and pivot points, decorative cylindrical elements in custom furniture or architectural metalwork, and short bearing liners in low-speed rotating applications where bronze's natural lubricity is an advantage.

ℹ️ Sizing note: All dimensions are nominal metric (mm). OD and ID are as-supplied stock dimensions. For precision bearing or press-fit applications, light finish machining is typically required. Confirm your required wall thickness — (OD − ID) ÷ 2 — before ordering.

✅ Key Features of These Brass Bronze Round Tubes

  • 🔩Wide OD × ID Matrix — 54 size combinations from 25×15mm to 95×75mm let you match exact bore and wall requirements without custom ordering.
  • 🛡️Corrosion-Resistant Bronze Alloy — Naturally resistant to oxidation and moisture, making these bronze tube sections suitable for outdoor fixtures, marine hardware, and humid environments.
  • ⚙️Machinable Stock — Bronze cuts cleanly with standard HSS or carbide tooling, allowing you to turn, bore, thread, or cut to length with minimal tool wear.
  • 📏Consistent 100mm Length — Each section is 100mm (≈3.94") long — a practical stock length for bushings, spacers, and short sleeve bearings that can be parted off as needed.
  • 🔄Self-Lubricating Surface Characteristics — Bronze's inherent lubricity makes these tubes well-suited as sleeve bearing liners in low-to-medium speed shaft applications where oil-impregnated bushings are not required.
  • 🏗️Structural Spacer & Standoff Use — The thick-wall variants (e.g., 40mm OD × 15mm ID with a 12.5mm wall) provide substantial compressive strength for use as column spacers, standoffs, and load-bearing cylindrical inserts.

❓ Frequently Asked Questions

How do I choose the right OD and ID for my application?

Measure the shaft or bore your tube needs to fit around or inside. The Inner Diameter (ID) should clear your shaft with a small tolerance — typically 0.1–0.5mm of clearance for a slip fit. The Outer Diameter (OD) determines the overall footprint. Wall thickness equals (OD − ID) ÷ 2. For example, a 50mm OD × 30mm ID tube has a 10mm wall on each side.

What load or pressure can these brass bronze tubes handle?

Bronze alloy tubes generally offer good compressive and tensile strength suitable for bushings, bearings, and structural spacers. Exact load ratings depend on wall thickness and alloy grade. For critical load-bearing applications, consult an engineer and confirm the specific alloy with us before ordering.

Are these tubes suitable for outdoor or marine use?

Bronze is naturally corrosion-resistant and performs well in humid, wet, and mildly saline environments. It is commonly used in marine hardware, outdoor fixtures, and plumbing fittings. For highly aggressive saltwater immersion, verify the specific alloy grade with us to confirm suitability.

What thread or fitting standards are compatible with these tubes?

These are unthreaded round tubes. They are compatible with standard metric bore fits and can be machined to accept metric or imperial threads. The OD and ID dimensions follow metric sizing (mm). If you need a specific thread tapped or a press-fit tolerance, the tube can typically be machined to suit.

How do I convert the mm dimensions to inches?

Divide mm by 25.4 to get inches. Quick reference:

  • 25mm ≈ 0.98"
  • 50mm ≈ 1.97"
  • 75mm ≈ 2.95"
  • 100mm (length) ≈ 3.94"

Use these to cross-reference with imperial-spec drawings or tooling.

Can I cut or machine these tubes to a custom length?

Yes. Bronze machines cleanly with standard HSS or carbide tooling. These 100mm (≈3.94") sections can be cut with a bandsaw, lathe, or pipe cutter. Deburr cut ends before installation. If you need a length other than 100mm, contact us to discuss custom cuts.

Which size should I choose for a bushing or sleeve bearing?

For a bushing application, the ID should match your shaft diameter with a light clearance fit (typically H7/f7 or similar). Choose an OD that fits your housing bore. A thicker wall generally provides better load distribution — for most light-duty bushings, a wall thickness of 5–10mm is common.

Is the surface finish ready to use, or does it need machining?

These tubes are supplied in an as-cast or extruded finish typical of bronze stock. The OD and ID dimensions are nominally accurate but may have minor surface variation. For precision fits (e.g., bearing bores), light finish machining or honing is generally recommended.
