C59 Tin Bronze Tube — Precision Bushing Stock for Shafts, Bearings & Mechanical Assemblies
Machinists, maintenance engineers, and DIY fabricators often struggle to find ready-to-machine bronze bushing stock in the exact wall thickness they need — especially when off-the-shelf bearings don't fit a non-standard bore. These C59 tin bronze tubes are stocked in 72 size combinations so you can select the precise OD and ID that matches your housing and shaft dimensions, then machine or press-fit to spec without wasting material on oversized bar stock.
Each piece is a single round tube cut to 100mm (≈3.94") in length, made from C59 tin bronze (CuSn6 equivalent — approximately 94% copper, 6% tin). Outer diameters range from 25mm (≈0.98") to 110mm (≈4.33"), and inner diameters range from 13mm (≈0.51") to 80mm (≈3.15"), giving wall thicknesses from approximately 5mm to 27.5mm depending on the size selected. All tubes are supplied in a plain, unthreaded, as-drawn or as-cast finish ready for secondary machining.
Typical applications include replacement bushings for agricultural equipment pivot pins, wear sleeves for hydraulic cylinder rods, custom bronze bearings for woodworking machinery, and sleeve inserts for vintage or custom automotive suspension components where standard bearing sizes are unavailable.
Compatibility Note: These are plain unthreaded round tubes. OD fits into a bored housing; ID fits over a shaft or pin. Verify your required OD, ID, and wall thickness before ordering — see the size selector above for all available combinations.
Sizing Tip: Wall thickness = (OD − ID) ÷ 2. Example: 60mm OD × 40mm ID = 10mm wall (≈0.39"). If your required dimensions are not listed, contact us before purchasing.
✅ Key Features of These C59 Tin Bronze Bushing Tubes
- C59 Tin Bronze Alloy — Copper-tin composition (CuSn6 equivalent) delivers better wear resistance and higher hardness than standard brass, making these tubes well-suited for sliding contact and bushing applications under moderate load.
- 72 Size Combinations — OD from 25mm to 110mm and ID from 13mm to 80mm cover a wide range of shaft and housing dimensions, reducing the need to machine down oversized stock for custom bronze bushing fabrication.
- Machinable & Cuttable — C59 tin bronze machines cleanly with standard HSS or carbide tooling. Each 100mm length can be parted, bored, turned, or drilled to your final dimensions with minimal tool wear.
- Corrosion-Resistant Composition — The tin content in this alloy generally improves resistance to oxidation and mild corrosion compared to plain copper or zinc-heavy brasses, extending service life in damp or lightly corrosive environments.
- Consistent 100mm Cut Length — A fixed 100mm (≈3.94") length provides enough material for most single-bushing applications and allows straightforward calculation of remaining stock after machining to final length.
- Press-Fit or Slip-Fit Ready — The plain OD surface is suitable for press-fitting into a bored housing or for light interference fits. The ID can be finish-bored or reamed to achieve the running clearance required for your shaft diameter.

❓ Frequently Asked Questions
How do I choose the right OD and ID for my application?
Measure the shaft or pin that will pass through the tube — that gives you the required ID. Then measure the bore in your housing or bracket — that gives you the required OD. Generally, leave 0.01–0.05mm of clearance on the ID for a sliding fit, or press-fit the OD into the housing for a fixed bushing. If you are unsure, contact us to confirm before ordering.
What load or pressure can these tin bronze tubes handle?
C59 tin bronze (CuSn6 equivalent) typically has a tensile strength of around 300–400 MPa and a hardness of approximately 70–90 HB, making it suitable for moderate bearing loads and bushing applications. Exact load capacity depends on wall thickness, fit, and lubrication. Contact us to confirm for critical load-bearing uses.
Can these tubes be used outdoors or in humid environments?
Tin bronze generally offers good corrosion resistance in freshwater and mildly humid environments. It is not recommended for prolonged exposure to seawater or strong acids without additional protection. For outdoor or marine applications, verify the specific environment before use.
Are these tubes compatible with metric or imperial thread standards?
These are plain (unthreaded) round tubes intended for machining, bushing, or sleeve applications. They do not come with pre-cut threads. You can machine threads to metric (ISO) or imperial (UNC/UNF) standards depending on your wall thickness and tooling setup.
How do I calculate the wall thickness from the OD and ID?
Wall thickness = (OD − ID) ÷ 2. For example, a 50mm OD × 30mm ID tube has a wall of 10mm (≈0.39"). Thicker walls generally provide more structural strength and allow more material removal during machining. For light-duty bushings, a wall of 5–10mm is typically sufficient; for heavy-duty applications, 15mm or more is common.
Is C59 tin bronze easy to machine or cut to a custom length?
Yes. C59 tin bronze is known for good machinability. It can be turned, bored, drilled, and cut with standard HSS or carbide tooling. The 100mm length can be cut down with a metal-cutting bandsaw or lathe parting tool. Always use appropriate cutting fluid for best surface finish.
What is the difference between C59 tin bronze and regular brass?
Standard brass (e.g., C36000) is primarily a copper-zinc alloy optimized for machinability. C59 tin bronze is a copper-tin alloy (typically 6% tin) that generally offers better wear resistance, higher hardness, and improved corrosion resistance compared to common brass grades, making it more suitable for bushing and bearing applications where surface durability matters.
