Introduction to Bimetal Bushing with Steel-CuPb30 Bronze Composition
Bimetal bushings made from Steel-CuPb30 bronze composition represent a pinnacle in bearing technology. By marrying the robustness of steel with the anti-friction properties of CuPb30 bronze, these bushings offer unparalleled performance.
Lead bronze-steel backed CuPb30 bimetal bearing bushes are crafted for situations that demand robust, low-friction bearings. These components are engineered by merging a steel base with a lead bronze (CuPb30) surface layer, achieving a synergy of durability, wear resistance, and adaptability. Here’s an in-depth look at their characteristics, uses, producers, and cost insights from the gathered information.
Characteristics
- Composition and Design: The CuPb30 bimetal bushing features a dual-layer design with a steel foundation and a lead bronze (CuPb30) coating. This configuration ensures high load endurance, superior fatigue resistance, and excellent wear protection.
- Hardness and Bearing Capability: With a liner hardness between 30 to 45 HB, CuPb30 bushes present a comparatively soft bearing face that molds to the shape of the associated shaft. They boast a load capacity reaching 30N/mm², making them apt for heavy-duty tasks.
- Heat Tolerance: These bushes are operational in temperatures as high as 150℃, catering to environments where thermal resistance is crucial.
Applications CuPb30 bimetal bushes find their application in various demanding settings, such as:
- Automotive and agricultural machinery engines and gearboxes, benefiting from their superior load capacity and resistance to wear and decay.

CuPb30 lead bronze-steel backed bimetal bearing bushes represent a dependable option for applications that require sturdy, low-friction bearings capable of supporting substantial loads and thriving under tough conditions. Their extensive utilization across different industries attests to their adaptability and the advantages they offer.
Understanding the Steel-CuPb30 Bronze Material Composition
The bimetal bushing, in this context, comprises two primary layers:
- Inner Layer (CuPb30 Bronze): This alloy is primarily composed of copper (Cu) and lead (Pb), with lead content around 30%. The CuPb30 bronze offers excellent wear resistance and low friction, making it ideal for bearing surfaces.
- Outer Layer (Steel): Providing the structural backbone, steel ensures the bushing’s overall strength and durability, making it resilient to external forces and stresses.
The synergy between steel and CuPb30 bronze offers a bushing that’s both robust and efficient in reducing friction.
Benefits of Using Steel-CuPb30 Bronze Bimetal Bushings
- High Load Capacity: The steel backing ensures that the bushing can handle significant loads.
- Exceptional Wear Resistance: CuPb30 bronze, with its inherent anti-friction properties, ensures minimal wear.
- Cost-Effective: Their durability translates to longer intervals between replacements, leading to cost savings.
- Versatility: Suitable for both oscillating and rotating movements.
- Excellent Thermal Conductivity: Effective heat dissipation prevents overheating during operation.
Typical Applications of Steel-CuPb30 Bronze Bimetal Bushings
Given their unique composition, these bushings find usage in:
- Automotive Systems: Especially in areas subjected to high loads like connecting rods, camshafts, and steering systems.
- Heavy Machinery: In cranes, excavators, and other heavy-duty machinery where wear resistance and load-bearing are crucial.
- Industrial Equipment: In gearboxes, pumps, and other rotating machinery.
- Aerospace: In components that require durability and efficient operation.
Maintenance and Care Tips for Steel-CuPb30 Bronze Bushings
Despite their robustness, proper care ensures the bushings’ longevity:
- Routine Inspection: Regularly check for signs of wear or damage.
- Lubrication: Periodic lubrication maintains the low-friction properties of the CuPb30 bronze.
- Cleaning: Ensure the bushings remain free from contaminants for optimal performance.
Bimetal bushings with Steel-CuPb30 bronze composition have carved a niche for themselves in various industries, thanks to their unique blend of strength and anti-friction properties. By understanding their composition, potential applications, and care requirements, industries can leverage their benefits to the fullest.
The CuPb30 bimetal bushing is a specialized bearing product designed for demanding applications, particularly in agricultural machinery like tractors and harvesters. Let’s delve deeper into the features, benefits, and applications of this bushing:
CuPb30 Bi-Metal Tractor and Harvester Bushing
Description:
The CuPb30 bimetal bushing combines the mechanical strength of steel with a sintered layer of CuPb30 alloy. This alloy is rich in lead (30% Pb), providing excellent sliding properties and wear resistance.
Key Features:
- High Lead Content: The CuPb30 alloy, with its high lead content, ensures superior embeddability and wear resistance. This means that if any foreign particles come into contact with the bearing surface, they are embedded into the soft alloy layer, preventing any damage to the mating shaft.
- Bi-Metal Construction: The combination of a steel backing with a CuPb30 alloy layer provides the perfect balance of strength and performance.
- Self-Lubricating: The CuPb30 alloy layer offers inherent lubricating properties, reducing the need for frequent external lubrication.
Benefits:
- Reduced Maintenance: The self-lubricating feature minimizes the need for regular maintenance, ideal for agricultural machines that operate in demanding conditions.
- Extended Equipment Life: The excellent wear resistance ensures that the machinery operates smoothly, reducing wear and tear and extending the lifespan of both the bearing and the equipment.
- Cost-Efficiency: With reduced maintenance and longer equipment life, the overall operational costs are lowered.
Applications:
- Tractors: These bushings can be used in various parts of tractors, such as pivot points, linkages, and hydraulic systems.
- Harvesters: Given the demanding conditions harvesters operate under, the CuPb30 bimetal bushings ensure smooth operation, especially in the cutting and collection mechanisms.
Why Choose CuPb30 Bi-Metal Bushings?
For those in the agricultural sector, equipment downtime can be costly. Using high-quality bushings like the CuPb30 bimetal variant ensures that machinery remains operational even in tough conditions, maximizing productivity and minimizing maintenance costs.
If you’re in the market for durable, reliable, and efficient bushings for your agricultural machinery, the CuPb30 Bi-Metal Tractor and Harvester Bushing is an excellent choice.

The term “akson burcu” identifies a particular kind of bushing known as a bimetal bushing. These bimetal bushings are composite bearings consisting of two layers of distinct metals fused together. Typically, the external layer is made of a low-friction material such as bronze, while the internal layer comprises a more robust metal, like steel. This design is intended to enhance performance in applications that are subject to high loads and stress, offering advantages over traditional single-metal bearings.
Within the realm of bimetal bushings, “burcu” specifically denotes the use of CuPb30 material in these bimetallic composite bearings. CuPb30, a type of lead bronze, features a hardness range of 30~45HB and is ideal for scenarios that demand excellent wear resistance and load-bearing capabilities. This material finds widespread use in components such as heavy vehicle balance axle bushings, automobile engines, chassis, motorcycle clutches, gear pump rubbers, and lifting equipment.
