Phosphor Bronze: A Prime Material for Bearings
specializing in Phosphor Bronze, A Detailed Exploration of C54400 Alloy: The Backbone of Phosphor Bronze Bushing Bearings
Phosphor Bronze is a type of bronze alloy that includes additions of tin and phosphorous. This alloy is acclaimed for its strength, resilience, and excellent resistance to wear and fatigue, making it a preferred material for bearing production. Bronze alloys, particularly Phosphor Bronze, have earned a solid reputation for their excellent mechanical properties and corrosion resistance. Among these alloys, the C54400, or C544 Phosphor Bronze, has become a favored choice for creating bushing bearings. In this article, we delve into the attributes and applications of C54400 alloy and its importance in bushing bearings.
C54400 Alloy: C544 Phosphor Bronze Bushing Bearings
C54400, also known as Phosphor Bronze Grade B, is a unique alloy consisting primarily of copper, tin, and phosphorus. The typical elemental breakdown includes about 88.2% copper, 4% tin, and 0.25% phosphorus. Its precise composition may vary slightly depending on the manufacturing process and source.
The alloy is renowned for its high strength, durability, and superior machinability compared to other bronze alloys. The addition of phosphorus not only improves stiffness and toughness but also enhances the alloy’s wear resistance and fine particle size during machining, which makes it ideal for manufacturing intricate parts with excellent surface finishes. The combination of strength, durability, and machinability makes C54400 a prime choice for manufacturing bushing bearings. Bearings made from this alloy are known for their excellent resistance to wear and corrosion, making them particularly well-suited to harsh, high-stress environments.
Phosphor Bronze – an overview, Bronze Bushing Bearings
090 Series Bronze Bushing Bearings
The 090 series bronze bushing bearings, fabricated from tin bronze alloy CuSn8, are recognized for their durability and high-load carrying capacity. Their surface features diamond-shaped oil holes that play a vital role in oil storage, facilitating lubrication and wear reduction.
These bearings exhibit excellent corrosion resistance, fatigue strength, and wear resistance, making them ideal for high-load, low-speed applications like agricultural machinery, construction machinery, and other heavy equipment.
092 Series Bronze Bushing Bearings
The 092 series bronze bushing bearings also employ tin bronze alloy CuSn8 as the primary material. These bearings differ from the 090 series as their working surface features lubrication through holes arranged at specific angles, ensuring easy oil film formation during startup and thereby reducing the starting friction coefficient.
Like the 090 series, the 092 series bearings offer superior bearing capacity, corrosion resistance, and wear resistance. They find extensive use in applications similar to the 090 series bearings.
Tin Bronze Bushings
Tin Bronze Bushings are created using a specific formula of high-density copper alloy strip. These bushings feature a surface that can be rolled into a diamond or hemispherical oil hole or oil tank, as per user requirements. The utilization of tin bronze alloy CuSn8 assures good fatigue strength, high-load carrying capacity, corrosion resistance, and wear resistance. Their use is widespread in machinery that operates under high-load and low-speed conditions.
CuSn8 rolled bronze bushes demonstrate excellent wear resistance and high bearing capacity, making them a cost-effective choice for various applications. The versatility of homogeneous bronze also supports the production of a wide range of products, including brass hot rolled sheets.
Wrapped Bronze Bearings
Wrapped bronze bearings and flanged bearings serve as excellent solutions in high-contamination environments. Their sliding surface is furnished with diamond-shaped lubrication pockets or hole patterns, assisting in maintaining lubrication and reducing friction. Produced according to ISO 3547, these bearings are ideal for applications requiring high corrosion resistance and durability.
