Product Specification

Graphite cast bronze bearings are a type of self-lubricating bearing that incorporates solid bronze plates with graphite plugs to achieve the self-lubricating property. Here's how the self-lubrication is realized in these bearings:

Material Composition: The bearing is made from a bronze alloy which is known for its good wear resistance and strength. The bronze is cast with graphite plugs that serve as a source of solid lubrication.

Graphite as a Lubricant: Graphite is a solid lubricant that has a natural ability to reduce friction between sliding surfaces. When the bearing is in motion, the graphite within the bronze matrix transfers to the contact surfaces, creating a thin, low-friction film that helps to reduce wear.

Initial Break-In Period: During the initial operation of the bearing, there is a break-in period where the transfer of material from the bearing to the mating surface occurs. This is a critical step in establishing the self-lubricating film on the contact surfaces.

Ongoing Transfer Process: After the initial break-in, the transfer process continues dynamically throughout the operational life of the bearing. The graphite continues to be transferred to the mating surface, maintaining a lubricating film that reduces friction and wear.

Maintenance-Free Operation: Unlike bearings that require regular application of external lubricants, graphite cast bronze bearings are designed to be maintenance-free. The graphite within the bronze provides a long-lasting source of lubrication, reducing the need for maintenance and extending the service life of the bearing.

Suitability for Various Applications: Due to their self-lubricating nature, graphite cast bronze bearings are suitable for applications where regular maintenance is difficult or where the environment is harsh, such as in high temperatures, contaminated conditions, or where there is a need for a dry-running system.

In summary, the self-lubrication in graphite cast bronze bearings is achieved through the use of graphite as a solid lubricant within the bronze matrix. This combination allows for a continuous transfer of lubricant to the contact surfaces, ensuring reduced friction, wear, and the need for maintenance.

FunctionaI in absence of oiI BRONZE GRAPHITE BUSHINGS Straight Bushings the can be used in circumstances where oiling and greasing is difficult or impossible and they perform excellent Iubrication even under low-speed and high Ioad circumstances.

Since the Iinear expansibility of solid Iubricant is greater than metallic matrix's, when the movement of solid lubricant bearings(VIIPLUS SLIDING BEARING BRONZE GRAPHITE BUSHINGS)start, the Iubricant is transferred onto the parts in abrasion thus realizing the self-lubrication.
