The FB092 bronze bushing, characterized by its CuSn8P0.3 composition, is a specialized bearing designed for various applications across different industries. This bushing is made from a cold-formed homogenous bronze (CuSn8)

The FB092 Wrapped Bronze Bearing, specifically made from CuSn8P0.3 bronze alloy, is a high-quality bearing designed for various applications across different industries. This bearing is characterized by its unique construction, which includes a matrix of bronze material (CuSn8) with uniformly distributed and orderly injection holes. These holes are not just for show; they play a crucial role in the bearing‘s operation by acting as lubricant reservoirs. This design ensures that a lubrication film is rapidly built up at the start of movement, significantly reducing friction and enhancing the bearing’s performance and lifespan

Bronze Bushings CuSn8P0.3 – FB092 Bronze Bearing

The FB092 bronze bushing, made with a CuSn8P0.3 composition, is an essential bearing for various industrial uses. This bushing, crafted from cold-formed, uniform CuSn8 bronze, boasts remarkable qualities like a high load-bearing capacity and outstanding lubrication features thanks to its through holes, making it perfect for a broad temperature spectrum. These attributes render it excellent for high-load, slow-motion scenarios found in construction, agriculture, and engineering equipment.

Key Attributes and Advantages:

  • Material Quality: Composed of CuSn8P0.3 or CuSn6.5P0.1 bronze alloy, the FB092 bushing offers superior resistance to wear and enhanced strength, ensuring longevity and resilience against wear.
  • Structural Design: Its compact, wrapped configuration, complemented by diamond-shaped lubrication indents on its surface, provides lubricant storage. This design promotes quick lubrication film formation when motion initiates, minimizing friction and boosting efficiency.
  • Self-Lubrication: The bushing’s holes act as lubricant reservoirs, offering ongoing lubrication and lowering the need for regular upkeep. This self-lubrication contributes to the bearing’s extended service life.
  • Load Endurance: Tailored to withstand substantial loads, the FB092 is ideal for environments with rough friction surfaces.
  • Resistance to Temperature and Corrosion: Capable of functioning in a vast range of temperatures and resistant to corrosion, the FB092 is suitable for demanding conditions.

Applications: The FB092 bronze bearing is utilized across different sectors due to its robust construction and material benefits:

  • Automotive: Employed in car suspension, steering mechanisms, and gearboxes.
  • Industrial Equipment: Used in CNC machines, production lines, conveyor systems, and other equipment needing high load support and slow operation.
  • Domestic Appliances: Integrated into household machines like washers and dryers.
  • Aerospace: Its resistance to high temperatures and wear aligns with the demands of aircraft systems.

Availability and Customization: Standard cylindrical and flanged versions of the FB092 bronze bushings are accessible, with special designs available to meet unique requirements, providing adaptability for diverse application demands. The CuSn6.5P0.1 bronze variant is also offered for different material needs.

In conclusion, the FB092 bronze bearing, featuring holes and constructed from CuSn8P0.3, serves as a reliable, versatile choice for numerous applications requiring high load support, longevity, and minimal upkeep. Its self-lubricating characteristic, wear and corrosion resistance, and ability to function across various temperatures make it a preferred option in the automotive, industrial machinery, domestic appliance, and aerospace sectors.

CuSn8P0.3 is a phosphor bronze alloy known for its composition that typically includes about 8% tin (Sn) and a trace amount of phosphorus (P), approximately 0.3%. This alloy is renowned for its excellent wear resistance, robustness, and corrosion resistance, making it a preferred choice for manufacturing components like bearings, bushings, and other parts that demand these attributes.

Material Composition and Characteristics:

  • Copper (Cu): The primary component, usually between 91.3% and 91.7%.
  • Tin (Sn): Constitutes about 8% to 8.5%, enhancing the alloy’s strength and resistance to wear.
  • Phosphorus (P): At about 0.3%, it boosts the material’s strength and ease of machining.

Mechanical Attributes:

  • Tensile Strength: Ranges from 370 MPa to over 740 MPa, varying with the material’s condition.
  • Yield Strength: Has a minimum of 250 N/mm², with maximum values dependent on the material’s state, possibly exceeding 700 MPa.
  • Elongation: Approximately 40%, showing notable ductility.
  • Hardness: Generally falls between 90-120 HB (Brinell Hardness).
  • Coefficient of Friction: Varies between 0.08 and 0.25.

Thermal and Electrical Properties:

  • Melting Point: About 1040°C.
  • Density: Roughly 8.8 g/cm³.
  • Thermal Conductivity: Stands at 58 W/(m*K) for the bearing material.
  • Electrical Conductivity: Estimated at 13% IACS at 20°C.
  • Coefficient of Thermal Expansion: 18.5 x 10^-6/K.

Additional Features:

  • Corrosion Resistance: Exhibits strong resistance against various environments but is vulnerable to certain substances like ammonia and oxidizing acids.
  • Machinability: Considered good, attributed to the phosphorus content.
  • Weldability: Compatible with numerous welding methods.
  • Formability: Effective when cold, less so when hot.

Applications: CuSn8P0.3 phosphor bronze is utilized in various sectors due to its high strength, resistance to wear, and corrosion resilience, ideal for components facing friction and wear in tough settings. Common applications include:

  • Bearings, bushings, and sliding elements.
  • Automotive industry components.
  • Electrical engineering parts, such as connectors and springs.
  • Machinery in paper, textile, and chemical industries.
  • Mechanical and apparatus engineering.
  • Shipbuilding components.

This material is selected for its ability to combine durability, resistance to wear, and corrosion protection, essential for parts operating under friction and wear in demanding environments.
