Flange wrapped split bronze bearing bushings are designed for self-lubrication, crafted from bronze, and feature a split design that facilitates straightforward installation. These bushings excel in both radial and axial movements, making them perfect for use in machinery that operates within gritty conditions, enduring shock loads, and vibrations. Constructed from materials like CuSn8 bronze, these bushings boast integrated lubricant reservoirs on their surfaces, which provide self-lubrication and enhance performance while minimizing the need for additional lubrication.
The bushings’ split configuration is achieved by rolling a rectangular metal blank into a cylindrical form, which simplifies the process of assembly and disassembly. This design choice not only makes them highly versatile but also ensures they can be easily integrated into or removed from various machinery setups.
Owing to their robust load-bearing capacity, resistance to corrosion, and adaptability to challenging operational environments, these bushings find extensive applications across multiple sectors. Industries such as construction, agriculture, automotive, and engineering benefit from their durability and performance.
With attributes like high density, substantial bearing capacity, excellent wear resistance, and an extended lifespan, these bushings are particularly well-suited for heavy-duty applications. They are commonly employed in lifting machinery, automotive tractor chassis, the machine tool sector, and mining equipment, where their reliability and efficiency are of paramount importance.
C86300 (SAE 430B) Manganese Bronze is renowned for its durability and resistance to corrosion, making it perfectly suited for applications that demand high load capacity at low speeds. This alloy excels in environments requiring superior wear properties and substantial bearing strength. Although it boasts impressive strength, C86300 manganese bronze cannot be heat-treated. It requires consistent lubrication for optimal performance and is best paired with hardened shafts. The inclusion of lead in its composition enhances its machinability, without significantly altering its mechanical characteristics.
