Custom Segment Carbon Self Lubricating Bushings For Machinery Industry
Custom Segment Carbon Graphite Impregnated Bushings For Multi Applications
Segment graphite bushings, also known as segmented carbon graphite bushings, are a specific type of graphite bushing design commonly used in pump applications. These bushings are designed with segmented or split construction, where the bushing is divided into multiple sections or segments.
The purpose of segmenting the bushing is to allow for flexibility and ease of installation. The segments can be compressed or expanded during installation, allowing them to fit into the pump housing or other components with a tight tolerance. Once installed, the segments come together to form a complete bushing that provides the necessary support and lubrication.
