SELF-LUBRICATING BUSHINGS WITH GRAPHITE INSERTS
Bushes in cast bronze based material (CuZn25Al5Mn4Fe3) with special solid inserts, maintenance-free, particularly suitable for oscillating and intermittent movements where it is difficult to form an oil filter.
The metal base supports high loads while the solid graphite insert provides the lubricant necessary for optimal operation at low sliding speeds and high surface temperatures. Excellent corrosion resistance, suitable for use in harsh chemical environments or with presence of water.
Self-lubricating bushings with graphite inserts are components used to reduce friction and wear within a machine or mechanical system. Self-lubricating bushings are designed to operate without the need for external lubrication, as they contain an intrinsic lubricating material that gradually releases during movement. The graphite inserts inside self-lubricating bushings play a crucial role in the lubrication process. Graphite is a solid material resistant to friction that can act as a solid lubricant. Its layers of atoms slide easily over each other, reducing friction between moving surfaces and preventing wear.
When the self-lubricating bushing is subjected to a load or movement, friction between the surface of the bushing and that of the shaft or pin in which it is inserted causes material friction. During this process, the graphite inserts gradually consume, releasing a lubricating layer that intervenes between the moving surfaces, reducing friction and wear.
Self-lubricating bushings with graphite inserts are often used in industrial applications such as heavy machinery, commercial vehicles, manufacturing plants, and other situations where it is necessary to reduce friction and wear. These components offer an effective solution for autonomous lubrication, eliminating the need for external lubricants and reducing required maintenance.
