Custom Bronze Bushings – Bronze Bushes Suppliers, flange bush bronze plain bearings made of CuSn8 with lubricating holes:
Producing various self-lubricating bushings, can do your drawings and custom jobs for you. Metric Flanged Wrapped Bronze Bush, wrapped bronze bushings are particularly well suited for applications where high levels of contamination make relubrication necessary. The sliding surface of the wrapped bronze bushing contains diamond shaped pockets that must initially be filled with grease. The pockets act as reservoirs to progressively release lubricant during operation. Wrapped bronze bushings are made entirely of bronze, CuSn8. The bushings are produced from strips which are then wrapped and calibrated.
Benefits: Insensitive to contaminated environments, resistant to shock loads and vibrations at slow speeds, good resistance to corrosive environments

Unlock the Power of Custom Bronze Bushes: Your Ultimate Guide to Self-Lubricating Bushings
Our custom bronze bushing at a glance. Ready to Eliminate Grease from Your System?
When it comes to precision engineering and high-performance machinery, bronze bushes are an indispensable component. Known for their durability, low friction, and self-lubricating properties, bronze bushes are widely used in various industries, from automotive to manufacturing. But what if you need something more tailored to your specific requirements? That’s where custom bronze bushes come into play. In this blog post, we’ll explore everything you need to know about custom bronze bushes, including materials, grades, types, and how we can bring your designs to life.
What Are Bronze Bushes?
Bronze bushes, also known as bronze bearings, are cylindrical components designed to reduce friction between moving parts. They are typically used in applications where high load capacity, wear resistance, and low maintenance are critical. Bronze bushes are self-lubricating, meaning they can operate smoothly without the need for external lubrication, making them ideal for harsh environments or hard-to-reach areas.

Bronze Bushes Material and Grades
The performance of bronze bushes largely depends on the material and grade used. Here are some of the most common bronze alloys used in bush manufacturing:
- Phosphor Bronze (C51000, C54400): Known for its excellent wear resistance and high strength, phosphor bronze is ideal for heavy-duty applications.
- Aluminum Bronze (C95400, C95500): Offers superior corrosion resistance and is suitable for high-load and high-temperature environments.
- Lead Bronze (C93200, C93700): Contains lead for improved self-lubricating properties, making it perfect for applications where lubrication is challenging.
- Silicon Bronze (C87300): Combines strength with corrosion resistance, often used in marine and outdoor applications.
Each material has unique properties, and our team can help you select the best alloy for your specific needs.
Types of Bronze Bushes
Bronze bushes come in various types, each designed for specific applications. Some of the most common types include:
- Solid Bronze Bushes: Made from a single piece of bronze, these bushes are highly durable and suitable for high-load applications.
- Flanged Bronze Bushes: Feature a flange at one end to provide additional support and prevent axial movement.
- Self-Lubricating Bronze Bushes: Embedded with lubricants like graphite or oil, these bushes reduce friction and require minimal maintenance.
- Split Bronze Bushes: Designed with a cut along the length, these bushes are easy to install and replace without disassembling the entire machinery.
- CNC Groove Bronze Bushes: Custom grooves can be machined into the bushes to improve lubrication distribution and enhance performance.
Cast Bronze Bushes: Comprehensive Overview
1. Definition and Composition
2. Manufacturing Processes
- Sand Casting: Suitable for low to medium volumes; cost-effective but may require post-machining.
- Centrifugal Casting: Produces denser, more uniform structures ideal for cylindrical shapes, enhancing mechanical properties.
Cast bushes are distinct from sintered (powder metallurgy) variants, which are often oil-impregnated.
3. Key Properties
- High Load Capacity: Withstands heavy static/dynamic loads.
- Wear Resistance: Ideal for low-speed, high-load applications.
- Corrosion Resistance: Performs well in marine/chemical environments.
- Thermal Conductivity: Dissipates heat effectively.
- Self-Lubricating Options: Some alloys incorporate graphite or oil pockets.
4. Applications
- Industrial Machinery: Pivot points, hydraulic cylinders.
- Marine: Propeller shafts, rudder bearings.
- Automotive: Suspension bushings, kingpins.
- Construction Equipment: Joints and linkages.
5. Advantages
- Superior to plastics in load/temperature tolerance.
- More corrosion-resistant than steel in wet environments.
- Minimal maintenance with proper lubrication.
6. Disadvantages
- Higher cost and weight compared to polymers.
- Less suitable for high-speed applications (e.g., better for <50 m/s).
7. Selection Criteria
- Load/Speed: Optimal for slow, heavy loads.
- Environment: Choose lead-free alloys for food/chemical industries.
- Lubrication: Specify oil grooves or graphite plugs if needed.
8. Installation & Maintenance
- Fitting: Use press-fit or shrinkage methods to avoid misalignment.
- Lubrication: Regular greasing intervals to prevent galling.
- Inspection: Monitor wear, overheating, or noise indicating issues.
9. Common Issues
- Wear/Overheating: Caused by poor lubrication or overloading.
- Corrosion: Select appropriate alloy for harsh environments.
- Galling: Prevent with proper installation and alignment.
10. Alternatives
- Sintered Bronze: Oil-impregnated for self-lubrication.
- Ball Bearings: Better for high-speed applications.
Conclusion
Cast bronze bushes excel in demanding, low-speed environments where durability and corrosion resistance are critical. Proper material selection, installation, and maintenance ensure longevity and performance.
