Bushing Material
They are ideal for a variety of heavy-duty applications, ensuring consistent performance even under harsh conditions.
Materials and Structure
Our bushings are made from top-grade bronze alloys that meet international standards, offering excellent corrosion resistance and high load-bearing capacity
- Outer Layer (Bronze Layer):
- The outermost layer is usually made of bronze, a copper-based alloy primarily consisting of copper and tin, with possible additions of other elements like zinc, lead, or phosphorus to enhance specific properties.
- The bronze layer provides mechanical strength and corrosion resistance, allowing the bearing to operate under minimal or no lubrication conditions.
- Middle Layer:
- Some high-performance wrapped bronze bushings incorporate an intermediate layer of special materials such as polytetrafluoroethylene (PTFE) or other plastics between the bronze and the shaft.
- This layer primarily serves to reduce friction and provide additional lubrication.
- Inner Surface:
- The inner layer may include lubrication grooves or oil holes designed to store lubricant, ensuring continuous lubrication.
- Such designs extend the bearing’s lifespan and reduce maintenance needs.

Advantages of wrapped bronze bushings
1. High-Quality Materials & Manufacturing Excellence
- Material: We use CuSn8 or CuSn6 high-strength bronze alloy, which is known for its excellent wear resistance and anti-corrosion properties. This ensures that the bushing performs well in both dry and lubricated environments, even in extreme conditions.
- Self-Lubricating Feature: The bushings are equipped with lubrication grooves or holes on the inner surface, allowing for automatic lubrication during operation, reducing the need for frequent maintenance and extending the product’s lifespan.
2. Precision Engineering & Tolerance Control
- Exacting Tolerance: Our Wrapped Bronze Bushings are manufactured with precision to meet international tolerance standards. The typical tolerance for most applications is H7/h8, but we also offer customized dimensions to fit specific client needs.
- Why This Matters: Tighter tolerances help reduce play and movement within the machinery, improving performance and reducing wear and tear, which ultimately lowers your operational costs.
- Customized Solutions: If your machinery requires bushings with special dimensions or specifications, we can provide tailor-made products to ensure a perfect fit for your application.
3. Outstanding Durability and Performance in Harsh Environments
- Wear and Corrosion Resistance: Designed to handle high loads and extreme environments (e.g., dust, mud, chemicals, or moisture), our bronze bushings significantly extend the service life of machinery, even in outdoor or abrasive working conditions
Mechanical and Physical Properties
- Max Static Load: 140 N/mm² – Indicates the maximum static load the bushing can withstand without deformation.
- Coefficient of Friction: Ranges from 0.05 to 0.20, varying with working conditions – Reflects the efficiency of movement and energy loss due to friction.
- Operating Temperature Range: -40°C to +130°C – Specifies the temperature range within which the bushing operates effectively.
- Max Sliding Speed: 2.5 m/s – The highest speed at which the bushing can operate without significant wear.
- Wear Rate: High wear resistance under normal operating conditions, suitable for medium load and low-speed applications – Highlights the durability of the bushing in typical usage scenarios.
Applications and Usage
- Suitable for Medium Load Applications: Ideal for applications where moderate loads are applied.
- Low-Speed Environments: Best used where operational speeds are relatively low to maximize lifespan and performance.
- Varied Temperature Environments: Capable of performing in a wide range of temperatures, from very cold to moderately hot.

What is a bushing?
What is the general process for manufacturing bushings?
Bushing manufacturing involves several key steps:
Material Selection: Choosing the appropriate material such as bronze, rubber, or plastic, depending on the application.
Forming: Techniques like casting, pressing, or extrusion are used to shape the raw material into a bushing.
Heat Treatment: For metal bushings, heat treatment is applied to increase strength and wear resistance.
Finishing: This step involves precision machining to achieve the required dimensional tolerances and surface finish.
Surface Treatment: A coating may be applied for corrosion resistance or lubrication purposes, such as zinc plating or Teflon coating.
What materials are commonly used in bushing production?
Common materials used in bushings include:
Bronze: Known for its durability and low friction, often used in heavy-duty applications.
Rubber: Used for vibration dampening in automotive and machinery applications.
Nylon/Polymer (like PTFE): Provides self-lubrication and is ideal for low-load, low-friction environments.
Steel: Used for high-load applications, often combined with a softer material like bronze or plastic as the lining.
How are bushing dimensions and tolerances maintained during production?
What surface treatments are used for bushings?
Bushings often undergo surface treatments to enhance their properties:
Zinc or nickel plating: Protects the metal surface from corrosion.
Teflon (PTFE) coatings: Provide low friction and self-lubricating properties.
Phosphating or black oxide coating: Improve wear resistance and reduce the potential for galling (severe adhesion between surfaces in motion).
What are the challenges in bushing production?
Key challenges include:
Maintaining precision: Ensuring dimensional accuracy across large production runs can be difficult, especially for complex shapes.
Material selection: Using the wrong material could result in failure under stress or environmental conditions.
Surface finish quality: Achieving smooth surface finishes is crucial to reducing friction and wear.
Can bushings be custom-made?
What environmental factors are considered in bushing production?
Manufacturers consider several environmental aspects:
Material sustainability: Using eco-friendly or recyclable materials.
Waste management: Minimizing production waste and properly handling hazardous materials.
Energy consumption: Optimizing energy use in production processes to reduce carbon footprint.
What is the purpose of a bushing?
How can I tell when a bushing needs to be replaced?
Signs that a bushing may need replacement include:
Cracks, splits, or visible damage.
Increased noise, such as squeaking or grinding.
Excessive play or movement in the component where the bushing is installed.
