When it comes to hydraulic pumps, reliability and durability are paramount. That's why cast bronze bushes made from CuSn5ZnPb5 material are a popular choice for hydraulic pump applications. These bushes feature a metric flange size and a groove type design, making them suitable for a wide range of hydraulic systems.
CuSn5ZnPb5, also known as Gunmetal or Phosphor Bronze, is a high-performance alloy that offers excellent wear resistance, good strength, and corrosion resistance. This material is ideal for hydraulic pump bushes as it can withstand the high pressures and temperatures encountered in these systems.
The metric flange size ensures compatibility with standard hydraulic pump components, making installation and replacement a breeze. The groove type design allows for better sealing and oil retention, ensuring smooth operation and extending the service life of the bush.
A major benefit of cast bronze bushes made from CuSn5ZnPb5 material is their low maintenance requirements. With proper installation and regular inspections, these bushes can last for extended periods of time without requiring replacement or repair. This reduces downtime and maintenance costs, making them a cost-effective solution for hydraulic pump applications.
In summary, hydraulic pump cast bronze bushes made from CuSn5ZnPb5 material with metric flange size and groove type design are a reliable and durable choice for low-maintenance hydraulic systems.
Our Cast Bronze Bushings are machined from continuous cast C93200 (SAE 660) bronze for superior quality and performance. The continuous casting process assures a uniform bronze structure throughout the bearing, free from porosity and hard particle inclusions commonly found in other cast processes.
Brass Bush,Heavy Duty Brass Bushes Supplier and Manufacturer,We can supply in a wide range of Hydraulic Pumps Bronze Bushing. The hydraulic pump bushing is widely used in many applications, such as industrial machines, power tools, automotive, etc. The bushing is highly resistant to abrasion, not completely exposed to water.
