A bronze bushing is a bearing component widely used in machinery and engineering applications, primarily made of bronze material. Its core concept is to provide support and guidance between moving parts, reducing friction and wear while effectively bearing loads. Bronze offers excellent wear resistance, load capacity, and corrosion resistance, making it suitable for conditions with high friction, heavy pressure, or insufficient lubrication. By installing a bronze bushing between the shaft and the housing, it extends equipment lifespan, reduces maintenance costs, and ensures smooth and reliable operation.
